## *THIS VIDEO IS OLD AND HAS BEEN REPLACED* ## I remade this video and split it into two parts: Day 11 (part 1) - Routing Fundamentals: th-cam.com/video/aHwAm8GYbn8/w-d-xo.html Day 11 (part 2) - Static Routing: th-cam.com/video/YCv4-_sMvYE/w-d-xo.html
After watching those 2 parts what should I watch next? Proceed to this? Free CCNA | Configuring Static Routes | Day 11 Lab 1 | CCNA 200-301 Complete Course. Thank you for the answer
ERRATA: At 7:20, the route should be '192.168.4.0/24 via 192.168.24.4, Gi0/1', NOT 'via 192.168.14.4'. Thanks to those who pointed it out for me! At 2:20, I misstated PC4's IP address (should be 192.168.4.1) and R4's IP address (should be 192.168.4.254)
It's OK, as you explained so well, I immediately saw the mistake. Doesn't matter at all. It is better to have good explainations with few errors than bad explanations without errors. In our case you give us so great keys to understand that thanking you it's just the strict minimum. ;)
plz jeremy, simply this lesson. all i hear is '192.168' 1000x times, it's really hard for newbies (especially with not native english) to stay with it on the network map - try to use just the end two octets, draw or mark addresses you are talking about - look at other cbt nuggets video - they dont't care how day mark the ip or the device - but it is usually always marked when they are talking about it and not using full ip all the time. just more human friendly would be better still very good course though !
When you have an obsession for repeating the ip addresses a gazillion times that happens. Why not say .4 instead of 192.168.1.4 when you have already said the network ID a million times already?
Jeremy, you are coming from God, you were born for this reason, please, never stop, the way how you explain everything is incredible, fabulous! If I thank you million times will be not enough! You make so many people happy. God bless you!
I’m a mother of a toddler. I read Wendell Odom’s CCNA prep book and then refer to your videos on topics that I don’t understand (like static routing…lol) My study time is when my baby naps. Your videos have given me a lot of confidence that I can pass my exam and start a career in networking. Thank you
Idk if anyone will read this, but I barely failed the exam yesterday, by such a small margin. If I had watched this video beforehand I would have been much better prepared. The exam asks a LOT of questions regarding routes and which one would be selected given a random destination address. Definitely good to know.
I learned some CCNA courses at a CCNA Academy, but I have to say that I’ve learned more and better from your videos. Great work. I’m waiting more videos from your channel. Thank you!
@@JeremysITLab 100% Agree. I'm about 25% through the official CCNA Academy curriculum, after finished the two free Network Basics courses, and I find it way more accessible to learn from these videos, the labs, and the flashcards. Cisco could learn a lot from people like you in making their materials more accessible and student-friendly.
You present and explain some heavy stuff exceptionally well and you make it interesting with the end-of-video quizzes, labs, flashcards. I've tried to understand this material for some time now and you make sense of it. First time I don't feel I have to look for more explanations. This is the last stop, it's where I get off for the time being and stick around :) This is fantastic Jeremy. Thank you!!
Hello Jeremy! Just wanted to say thank you so much for the effort and time you are putting on these videos!. I was actually drop out of my class because the teacher is super bad is not pedagogic at all and I was super lost, but now, after watching your videos finally things start to make so much sense. You explain so well and make it much easier. I really appreciate it. As soon as I get my student loan approved I will send you some crypto to support your channel :)
Hey Jeremy, thanks again. Many people in the comments have expressed a different opinion about how much you repeat the IP addresses, but in my opinion repetition is the key for learning so I appreciate the way you have structured the content.
Thank you, I'm glad you think so :) In future videos I'll probably avoid saying the entire address, as long as its totally clear exactly what address I'm referring to.
Getting so much value from these videos. Those ANKI cards on my Android. Handy for study at work or on the bus. I need to go through your lab series quite a bit.
This is on point... been trying to work packet tracer properly for 8 months. within 11 days I have a greater understanding. Hopefully, within the next three months, I can plan and build a vast network and understand what I am doing and document it properly.
i was planning to write my CCNA in 3months but i still have to wait till you will cover all the video because you are the only one lecturer on youtube who is clear on explanation... am even feeling ready to write but unfortunately i have to wait for the rest of the topics.... thanks a lot for sharing your knowledge
Thank you so very much, Jeremy, I am really impressed with how well you go through the explanations of the static routing, it is not an easy topic, in fact, is for me one of the most confusing for me after the spanning tree protocol and the selection of designated and block ports, but that will be another great topic. After watching this video about the static routes I can see things clearer and clearer, if it wasn't for this content you are creating I will definitely still be relying on "maybe, not too sure..." type of answers. Keep it up, you are one of the best in this right now. Thank you for the great information and in detail explanations!
Really you are awesome sir ,thank a lot .i heard about you and i am tring to understant your language and finally after few days i will understand then i realise that i never find a teacher like you at youtube 😊
Thank you for your efforts of making such great videos. You are the best teacher ever I have found on TH-cam. Without your help it would be very difficult for me.
You have done a great job in this CCNA series. I like your presentation above & beyond most other CCNA instructors I have looked at so far. Thank you for your systematic & thorough coverage of material. Thank you for your repeated labs that accompanied every topic. Thank you for being so articulate explaining the subject maters. Your explanation approach is superb. Thank you again. I will pay you for this great work you have done as soon as I get my network engineering job. I've gone through all 64 videos & using your training for my CCNA exam preparation. Hope you do a series for Cisco DevNet as well. Best Regards to you. Stay healthy.
The previous lesson took me about 10 replay and I had the chance to actually use the flashcard. Suddenly I realised that my memory was not half as bad as I thought it was. Actually I have a good memory, I just needed to practice it. This video however, easy for me, because I had the chance to cover this in other course. However, it's been a great opportunity to revise. Thank you Jeremy. Now I anctiously wait for the next video... :)
I have been recommending these videos to all of my friends. Thanks a lot for providing such an amazing content in a very engaging way and not to mention, truly appreciate the hands-on on Labs.
a traceroute from PC1 to PC4 at 25:36 would have shown that the packet had a successful route too. Love your vidoes btw, trying to get through them in a few weeks to reup my dusty ol' 640-607
I am a bit confused with those addresses and would like to comment about it and ask explanation but when I read the comments below it enlighten me now. Still confused but I will watch this video again. The prefix /8 on a class C blows my mind. Thanks anyway.
The /8 on the class C is called a 'summary' address. It's a great way to configure routes for MANY desinations with a single route. For example, instead of configuring separate routes to 192.168.1.0/24, 192.168.2.0/24, 192.168.3.0/24, 192.168.4.0/24, etc, you can configure a single route 192.168.0.0/16 (not /8 in this example, although 192.0.0.0/8 works too!) which covers ALL destinations from 192.168.0.0 to 192.168.255.255. Very useful!
Thank you for the fantastic content. Using you and the OCG and your videos help cement the ideas. I do have a serious question, why would anyone down vote great free content?
Got both the first and second quiz questions wrong , the second quiz Q I messed up with the mask saying 255.255.255.0 however nailed the last 3 and especially the last one damn happy I was looking in the right places and distinguishing between all that data what the best route would be taking in mind your short tip (/32>/24>/16>/8>/0), helps a lot since I'm self studying and self motivating
Its the video #19 of the course, and here is my first complain. As I remember as a former CCNA, configuring static routes were never as complicated as you explain it here.... It was pretty much easier according to me.... anyways, i will continue to watch the following videos because I want to get certified again,. Thanks.
Cleared up a lot of my questions on what happens. Thanks Nice that first quiz question I have to study more, and the last Quiz question I got half correct...So I should Study more
It's impossible to find a CCNA tutorial that is more detailed and goes more in-depth than yours do! Thank you Jeremy! Question though: Why did you configure PC1 with a default route and all other routers with static next hop address when sending a packet from PC1 to PC4? Why not configure PC1 with the next hop IP address as well? Is it because non-routable devices like PC1 can't execute the next-hop commands and can only use default gateways? Sorry, this might seem like a dumb question but I'm still trying to wrap my head around this. Thank you again!
Usually on a PC you just configure a default gateway (the router for the local network), or more commonly it automatically learns the default gateway via DHCP (to be covered later in the course). It can send the traffic directly to other PCs in the same LAN (connected to the same switch), and for everything else it can just send it to the router to be forwarded.
Hi Jeremy, thanks for sharing this great work in educating us. I think there might be a small mistake on 192.168.14.4 you have indicated in black, on top right of the video (around 7min & 40 sec of the video). The network between R2 & R4 is 192.168.24.4. Let me know if its a misunderstanding of mine. Thanks
Jeremy thank you very much for your hard work. I appreciate it man. Hey...check out around 7:30 min. in this video. Listen and read carefully. Thanks buddy
hi Jeremy....your free course for help us is very amazing you really the great job 🌼🌼🌼 thank you very much please let me know if you give the course for the ccnp exam. 🙏🙏🙏 thank you 🥰
Dear Mr. Jeremy, I have a project and I did your first 20 sessions which were very good. The project is to have a floor for 15 classes and in each classroom, there should be 20 PCs +10% extra. Each class cannot access It also says that each classroom must be isolated with no access to the other devices in the classrooms. I believe that I have to use switches in every classroom right and use subnetting since the budget is only 10,000 dollar
Thank you I had little doubt on the static router configuration and how to look at the cmd mde of the routing table and find out the answer. you gave me very clear picture. Thanks. good explanation
Thank you so much Jeremy. Very Clear Information. much appreciated sir. Are all up coming videos will be covering all CCNA exam 200-301 topics? Thanks a lot again my friend
Hi Jeremy. Your classes are a great help and I cannot thank you enough for the vivid explanation you give in each lecture. However, I did not understand one thing in this lecture. Why did you use Cisco router to simulate a PC? I have been trying to do the same lab and I cannot configure the default route from the PC.
Hi Jeremy, great job! How were you able to add a link to the topology between R1 and R4 (192.168.14.0/24/24 network)? I'm using model 2911 in Packet tracer , int Gig0/0-2 are all connected for both R1 & R4 and there's no extra interface to add the link between R1 & R4. Thanks
For these lecture videos I use GNS3, not Packet Tracer. However you can add extra interfaces in Packet Tracer, do a google search for 'packet tracer add modules', you can probably find a guide.
Thank you so much for doing these, I worked with routers a decade ago and this is explaining things I never fully understood. If the lab setup was a real life situation, would there be any reason to set a default route on R2? (I didn't set one for the lab)
Hi Jeremy! 1)will you complete the entire routing and switching part required for CCNA 200-301 till feb 2020 ? 2)for the rest of the content is neil anderson's course enough along with cert guide by cisco ? As i am planning to take the exam in 2nd week of March 2020.. Thanks for the videos.. the way you teach makes concepts very easy to comprehend! Keep making them.. I wait for the weekends to watch your latest video! Thank you sir!
Unfortunately I won't be finished by February, I guess it will take until the end of this year. But yes, Neil's course and Cisco's cert guide will cover the rest for you if you want to take the exam soon!
Hi Jeremy, apologies for asking so many questions, I really appreciate you taking the time to reply to me on top of your free courses. You say that 192.168.1.1/32 refers to only 1 specific address 192.168.1.1, but doesnt 192.168.1.1/24 do the same as well? My reasoning for this is that 192.168.1.1 before the mask already refers to a specific node ip address on a network, so why change the mask from /24 to /32 when a /24 mask can remind us that this is a class C network. Thanks!
When you write a static route to a /24 destination, you are saying 'match all destinations where the first 24 bits match the ones I specify'. So, you can't create a route to '192.168.1.1/24'. Because the last '.1' isn't included in the 24 bits you're telling the router to match against, that bit has to be 0 when you configure the route. If you want to create a route to a single host, use /32. If you want to create a route to a /24 subnet, use a /24.
Absolutely amazing videos!! May God bless you. Took only 2 days to complete all 11 day videos. I was never interested like this before, I think it's because of the labs that I'm so hooked up. What happened at 26:26? I could hear sirens hehe. Keep up the great work!
To progressively understand the meaning of the 0.0.0.0 /0 network, let’s have the following look even if it is not realistic at all (nevertheless the calculations allow to go further towards the meaning of 0.0.0.0 /0): If the network IP address is 0.0.0.0 and the mask is for instance 255.255.255.0 then all the IP addresses from 0.0.0.0 to 0.0.0.255 will be in the 0.0.0.0 /24 network (a little bit like in class C but not realistic at all in our case here because there are no such IP addresses). If the network IP address is 0.0.0.0 and the mask is for instance 255.255.0.0 then all the IP addresses from 0.0.0.0 to 0.0.255.255 will be in the 0.0.0.0 /16 network (a little bit like in class B but not realistic at all in our case here because there are no such IP addresses). If the network IP address is 0.0.0.0 and the mask is for instance 255.0.0.0 then all the IP addresses from 0.0.0.0 to 0.255.255.255 will be in the 0.0.0.0 /8 network (a little bit like in class A but not realistic at all in our case here because there are no such IP addresses). If the network IP address is 0.0.0.0 and the mask is for instance 0.0.0.0 then all the IP addresses from 0.0.0.0 to 255.255.255.255 (meaning all the possible IP addresses) will be in the 0.0.0.0 /0 network and that the point we wanted to reach!!!. Note that if the network IP address is 0.0.0.0 and the mask is for instance 255.255.255.255 then only this network IP address 0.0.0.0 will be in the 0.0.0.0 /32 network (not realistic at all).
@@JeremysITLab Thank you Jeremy, it is just an extension of what you already explained. Without your explainations I couldn't go this way. Thank you very much for all because you are really doing a great job. :)
@Jeremy’s IT Lab Hiya, What am I missing here ? @22:10 on R1 where the static route is directly connected via G0/0...why does it say directly connected when the hop is 2 routers away ? Is this a Cisco nomenclature thing, cause it’s really not directly connected...Does it just think it’s, on account of pointing to the exit interface rather than R2’s next hop interface ? Thanks
Good question! As you said, that's just how it's displayed in the routing table when you specify the 'exit interface' instead of 'next-hop IP' in the static route command. It will display as 'directly connected', even though it isn't.
Fantastic series. My only quibble is once you could drop the 192.168 pre-fix for everything as normally you would shorten it to .1.1 or .4.1 as everyone knows the prefix. Real world talk since we're past basic addressing, and prob help you. Only other is it is really distracting to flip back and forth from diagram to cli. Prob did this to make viewing easier, however its almost worse since its jarring. Split screen with cli on one side and diagram on the other would be nice. I guess I'll go 3 for 3. Would make it a lot easier since the actual addresses don't matter to much aside from showing they are in the rfc1918 private address space, however could just make your router 1.1.1.1, 2.2.2.2, etc, along with similar for switches and pc. I'm just reviewing to update my ccna, and otherwise really appreciate your time and effort.

plz jeremy, simply this lesson. all i hear is '192.168' 1000x times, it's really hard for newbies (especially with not native english) to stay with it on the network map - try to use just the end two octets, draw or mark addresses you are talking about - look at other cbt nuggets video - they dont't care how day mark the ip or the device - but it is usually always marked when they are talking about it and not using full ip all the time.
just more human friendly would be better
still very good course though !
Thanks i didn't know you have corrected 7:20 on the comments here below
When you have an obsession for repeating the ip addresses a gazillion times that happens. Why not say .4 instead of 192.168.1.4 when you have already said the network ID a million times already?

I am a bit confused with those addresses and would like to comment about it and ask explanation but when I read the comments below it enlighten me now. Still confused but I will watch this video again. The prefix /8 on a class C blows my mind. Thanks anyway.
The /8 on the class C is called a 'summary' address. It's a great way to configure routes for MANY desinations with a single route. For example, instead of configuring separate routes to 192.168.1.0/24, 192.168.2.0/24, 192.168.3.0/24, 192.168.4.0/24, etc, you can configure a single route 192.168.0.0/16 (not /8 in this example, although 192.0.0.0/8 works too!) which covers ALL destinations from 192.168.0.0 to 192.168.255.255. Very useful!
Thanks for all the details Jeremy Sir, many thanks from Chad in Africa ;)
Thanks for watching :)
Jeremy you are really an amazing teacher...God Bless you!!!!!!!!!!
now i have more confidence. after watching this repeatedly.
Thank you for the fantastic content. Using you and the OCG and your videos help cement the ideas. I do have a serious question, why would anyone down vote great free content?
Can't please everyone ;)
Got both the first and second quiz questions wrong , the second quiz Q I messed up with the mask saying 255.255.255.0 however nailed the last 3 and especially the last one damn happy I was looking in the right places and distinguishing between all that data what the best route would be taking in mind your short tip (/32>/24>/16>/8>/0), helps a lot since I'm self studying and self motivating
thanks a lot, you are really help me to prepare my ccna exam, you are clear and you explain with very understanding way with right order of context
Thank you, I'm glad to hear that :)
Its the video #19 of the course, and here is my first complain. As I remember as a former CCNA, configuring static routes were never as complicated as you explain it here.... It was pretty much easier according to me.... anyways, i will continue to watch the following videos because I want to get certified again,. Thanks.
Do you have any questions?
Thank you for the explanation of Routing. This best explanation I found
Cleared up a lot of my questions on what happens. Thanks
Nice that first quiz question I have to study more, and the last Quiz question I got half correct...So I should Study more
Thanks for this great course no words.
Thank you :)
Thank you Jeremy.. Can’t wait for the new video.
Thank you, new video coming every week :)
It's impossible to find a CCNA tutorial that is more detailed and goes more in-depth than yours do! Thank you Jeremy!
Question though: Why did you configure PC1 with a default route and all other routers with static next hop address when sending a packet from PC1 to PC4? Why not configure PC1 with the next hop IP address as well? Is it because non-routable devices like PC1 can't execute the next-hop commands and can only use default gateways? Sorry, this might seem like a dumb question but I'm still trying to wrap my head around this. Thank you again!
Usually on a PC you just configure a default gateway (the router for the local network), or more commonly it automatically learns the default gateway via DHCP (to be covered later in the course). It can send the traffic directly to other PCs in the same LAN (connected to the same switch), and for everything else it can just send it to the router to be forwarded.
I'm so happy I figured out question 5 lol I'm learning xD
Really appreciate the way you explain everything. GBU
Thank you :)
thanks Jeremy， it is becoming more and more interesting
Thanks Alex, glad to hear that!
You are a good guy , God bless you
Hi Jeremy, thanks for sharing this great work in educating us. I think there might be a small mistake on 192.168.14.4 you have indicated in black, on top right of the video (around 7min & 40 sec of the video). The network between R2 & R4 is 192.168.24.4. Let me know if its a misunderstanding of mine. Thanks
ya i figured but as he was telling he mentioned 24,
Indeed that is a mistake, thank you for pointing that out!
I was looking for this comment lol
Wow. I learned a lot more compared to what I was initially looking for. Thank you.
You're making these really easy to follow. Thanks!
Jeremy thank you very much for your hard work. I appreciate it man. Hey...check out around 7:30 min. in this video. Listen and read carefully. Thanks buddy
Check the errata in the pinned comment.
Great job Jeremy, keep up the good work.
amazing lesson. the graphics help so much.
Thanks :)
hi Jeremy....your free course for help us is very amazing
you really the great job 🌼🌼🌼
thank you very much
please let me know if you give the course for the ccnp exam. 🙏🙏🙏
thank you 🥰
I really appreciate your content! I think is the best out there!
each day i believe i'm geting readier and readier for the real thing
Dear Mr. Jeremy, I have a project and I did your first 20 sessions which were very good. The project is to have a floor for 15 classes and in each classroom, there should be 20 PCs +10% extra. Each class cannot access It also says that each classroom must be isolated with no access to the other devices in the classrooms. I believe that I have to use switches in every classroom right and use subnetting since the budget is only 10,000 dollar
In all floors there should be a network printer where staff and students are allowed to make printouts
Thank you I had little doubt on the static router configuration and how to look at the cmd mde of the routing table and find out the answer. you gave me very clear picture. Thanks. good explanation
Thanks for your comment, I'm glad to hear that!
u are the best teacher i watch
Thank you :)
Thank you so much Jeremy. Very Clear Information. much appreciated sir.
Are all up coming videos will be covering all CCNA exam 200-301 topics? Thanks a lot again my friend
Yes, I will cover all of the exam topics. When I finish, I will cover different things, maybe CCNP.
Thank you again for another wonderful video.
Loving the videos. Keep up the great work!
Excellent as always; Marks 10/10
just became a member....cheehoo!!!
Thank you so much! Cheers!
Fantastic job! Thanks! Please continue
Thanks, I will!
thanks a lot
great and excellent explanation really clear and covers every single info
really thanks for your massive effort
Thank you!!!
You are one of the best in the field
Hi Jeremy. Your classes are a great help and I cannot thank you enough for the vivid explanation you give in each lecture. However, I did not understand one thing in this lecture. Why did you use Cisco router to simulate a PC? I have been trying to do the same lab and I cannot configure the default route from the PC.
thanks jeremy brother. tons of love.
Thanks J, always informative
Thanks as always, Glenn!
Would love to hear you regarding in what case we should use next hop and what for exit interface
Dear Jeremy request you to perform the above example in packet tracer for more easy understanding . Will be very thankful to you ..
Check out the lab video! th-cam.com/video/XHxOtIav2k8/w-d-xo.html
Hi Jeremy, great job! How were you able to add a link to the topology between R1 and R4 (192.168.14.0/24/24 network)? I'm using model 2911 in Packet tracer , int Gig0/0-2 are all connected for both R1 & R4 and there's no extra interface to add the link between R1 & R4. Thanks
For these lecture videos I use GNS3, not Packet Tracer. However you can add extra interfaces in Packet Tracer, do a google search for 'packet tracer add modules', you can probably find a guide.
Thank you so much for doing these, I worked with routers a decade ago and this is explaining things I never fully understood. If the lab setup was a real life situation, would there be any reason to set a default route on R2? (I didn't set one for the lab)
In a network like this, not really.
Hi Jeremy!
1)will you complete the entire routing and switching part required for CCNA 200-301 till feb 2020 ?
2)for the rest of the content is neil anderson's course enough along with cert guide by cisco ?
As i am planning to take the exam in 2nd week of March 2020.. Thanks for the videos.. the way you teach makes concepts very easy to comprehend!
Keep making them.. I wait for the weekends to watch your latest video!
Thank you sir!
Unfortunately I won't be finished by February, I guess it will take until the end of this year. But yes, Neil's course and Cisco's cert guide will cover the rest for you if you want to take the exam soon!
Hi Jeremy, apologies for asking so many questions, I really appreciate you taking the time to reply to me on top of your free courses.
You say that 192.168.1.1/32 refers to only 1 specific address 192.168.1.1, but doesnt 192.168.1.1/24 do the same as well? My reasoning for this is that 192.168.1.1 before the mask already refers to a specific node ip address on a network, so why change the mask from /24 to /32 when a /24 mask can remind us that this is a class C network. Thanks!
When you write a static route to a /24 destination, you are saying 'match all destinations where the first 24 bits match the ones I specify'. So, you can't create a route to '192.168.1.1/24'. Because the last '.1' isn't included in the 24 bits you're telling the router to match against, that bit has to be 0 when you configure the route. If you want to create a route to a single host, use /32. If you want to create a route to a /24 subnet, use a /24.
great explanation Jeremy ..
Thanks! :)
Absolutely amazing videos!!
May God bless you.
Took only 2 days to complete all 11 day videos.
I was never interested like this before, I think it's because of the labs that I'm so hooked up.
What happened at 26:26?
I could hear sirens hehe.
Keep up the great work!
Thank you, I'm glad you like the videos!
I think there's a fire station near my house, those sirens often disturb my recording!
To progressively understand the meaning of the 0.0.0.0 /0 network, let’s have the following look even if it is not realistic at all (nevertheless the calculations allow to go further towards the meaning of 0.0.0.0 /0):
If the network IP address is 0.0.0.0 and the mask is for instance 255.255.255.0 then
all the IP addresses from 0.0.0.0 to 0.0.0.255 will be in the 0.0.0.0 /24 network (a little bit like in class C but not realistic at all in our case here because there are no such IP addresses).
If the network IP address is 0.0.0.0 and the mask is for instance 255.255.0.0 then
all the IP addresses from 0.0.0.0 to 0.0.255.255 will be in the 0.0.0.0 /16 network (a little bit like in class B but not realistic at all in our case here because there are no such IP addresses).
If the network IP address is 0.0.0.0 and the mask is for instance 255.0.0.0 then
all the IP addresses from 0.0.0.0 to 0.255.255.255 will be in the 0.0.0.0 /8 network (a little bit like in class A but not realistic at all in our case here because there are no such IP addresses).
If the network IP address is 0.0.0.0 and the mask is for instance 0.0.0.0 then
all the IP addresses from 0.0.0.0 to 255.255.255.255 (meaning all the possible IP addresses) will be in the 0.0.0.0 /0 network and that the point we wanted to reach!!!.
Note that if the network IP address is 0.0.0.0 and the mask is for instance 255.255.255.255 then
only this network IP address 0.0.0.0 will be in the 0.0.0.0 /32 network (not realistic at all).
Thanks for this comment! I think it will help others understand.
@@JeremysITLab Thank you Jeremy, it is just an extension of what you already explained. Without your explainations I couldn't go this way. Thank you very much for all because you are really doing a great job. :)
Hi Jeremy I am Anand I am following your CCNA course. I find it very helpful for my CCNA Completion. I need help for flashcards
@Jeremy’s IT Lab
Hiya,
What am I missing here ?
@22:10 on R1 where the static route is directly connected via G0/0...why does it say directly connected when the hop is 2 routers away ?
Is this a Cisco nomenclature thing, cause it’s really not directly connected...Does it just think it’s, on account of pointing to the exit interface rather than R2’s next hop interface ?
Thanks
Good question! As you said, that's just how it's displayed in the routing table when you specify the 'exit interface' instead of 'next-hop IP' in the static route command. It will display as 'directly connected', even though it isn't.
Fantastic series. My only quibble is once you could drop the 192.168 pre-fix for everything as normally you would shorten it to .1.1 or .4.1 as everyone knows the prefix. Real world talk since we're past basic addressing, and prob help you.
Only other is it is really distracting to flip back and forth from diagram to cli.
Prob did this to make viewing easier, however its almost worse since its jarring.
Split screen with cli on one side and diagram on the other would be nice.
I guess I'll go 3 for 3. Would make it a lot easier since the actual addresses don't matter to much aside from showing they are in the rfc1918 private address space, however could just make your router 1.1.1.1, 2.2.2.2, etc, along with similar for switches and pc.
I'm just reviewing to update my ccna, and otherwise really appreciate your time and effort.
Ok
