The preempt command was left off of R2, which is why you weren't seeing HSRP failover to R2 when S1/0 was brought down on R1. The rest of the lab is great. Thanks for the video.
Congratulations for your lesson on HSRP but especially for the pronunciation of your English, understandable even for those who are not native speakers. Thank you very much.
Dan the friggin man to the rescue. I've been stubbornly going at this solo for 2 hrs now, trying to complete a homework assignment. Thanks so much for taking the time to create such helpful and quality videos. - Cheers
Hello Dan, I've noticed that you have a mistake in configuration on from R1, you typed standby track G0/1 wich will by default set HSRP group 0 for that particular command. The correct way is to specify the group for that command and optional the decrement value
@Stancu Mihai You are correct. My running-config shows "standby 0 track GigabitEthernet0/0" which is incorrect. It should actually read "standby 1 track GigabitEthernet0/0".
Hello mister, can that cable between the routers(those that have holes in between) be a serial cable the red one ? and if so, will the hsrp still work?
Hi danscourses , thanks for all the vids. I an safely say that you have helped me get through CCNA1 - 4 and deff helped me with Netriders, i came 5th in Sub Sahara Africa this year. :) I have a question though. How would you go about configuring HSRP on 2 L3 switches with multiple VLANS? I also have DHCP pools that are population each VLAN.Regards Mike
At 14:21min you can see that the tracking id is different from the rest. The tracking id is 0 instead of 1, is that correct? Would that be the reason why the standby router did not show the status change messege?
Martin Larrosa Hmm. I think more correct is command: r(config-if)# standby 1 track gigabitEthernet 0/1 . Becose we can put group number too on track command. Dont sure thet needs. As we can see all works properly...
Hi dan can you make a video regarding HSRP in Multiple Vlan? please I really need to know how it going to be configured. And by the way our team would like to thank you for the generosity you have in sharing some of your knowledge in Cisco. A big big big thank you sir dan... KUDOS!
Hey mate, thanks for all the videos they are really helpful! just wanted to ask a question about the config you have here, shouldn't the "standby X preempt" command be on all the routers standby interfaces so when the priority changes from a lost link the other routers with a higher priority can go into a active state?
David Smith You are right. Unless configured to preempt, a standby router will become active only when the standby holdtime expires (10 sec by default), meaning no Hellos at 224.0.0.2:1985 (UDP) for 10 sec.
hi dan! my only question on the hsrp is how to configure dhcp on it? do you create the dhcp on the hsrp routers or do you create it on the edge router and configure ip-helper on the hsrp routers? i saw a vid that showed how dhcp is setup on the hrsp routers however, i couldn't find the command ip dhcp-server in the packet tracer. i only use packet tracer and I'm studying for ccna. appreciate your advise.
Hey Ryan, you can achieve these multiple ways - You could have DHCP pool setup on both routers i.e. /24 and when a PC broadcast out its Discover to find a DHCP server both routers will respond with an offer but the PC will only pick the first one it received. If there are two DHCP servers, why are there no conflicts? - Before an IP is given from any pool DHCP checks to see if that IP is being used on the network and hopefully if any of the DHCP pools on any router has given an IP to the PC/Host the other should detect the IP is being used on the network and not give it out. But it’s possible when DHCP checks the PC/Host doesn’t respond and as such duplicate IPs may appear on the network causing problems for users. A safer option (Depending on design) could be to split your pool across two devices i.e. 2x /25 on each router, rather than both being configured with the same /24, but if a router were to fail your available dynamic IPs will reduce, so you need to ensure your entire estate can be handled by a single router in an event of a failure A better option would be to utilise DHCP-Relay (IP-Helper Address) on both routers so the messages are sent to a remote server off the local network to be centrally handled. This would also mean, any router receiving the request could handle a response and since DHCP is only being handed out by a central device there are no conflicts Hope this helps
hi dan, does it work without edge router? I have 2 router with different 2 isp provider and I want to run it with redundant internet connection. any inputs? thanks!
Dan I'm curious about your ISP-A configuration. Could you talk a bit about how you made it. I don't seem to be able to run your download even though im using 6.1. I was hoping to recreate this. Thanks.
Dan when can we have the CCNP video tuts because I've been through a few others after yours to cover as much as possible before the exam, even though your CCNA tut's are the longest in terms of numbers of vids covering everything but the others having shorter running times always became a drag for me.
hi! my question is that during the HSRP do the packets are shared on bpth routes like OSPF do load balancing or it just uses a single route until the router goes down ?
No load balancing with HSRP. You need to use GLBP to load balance. But if you have multiple VLANs (IP subnet) you can distribute them on the two routers.
When we use HSRP do we need to configure the interface in your exam g0/0 with real ip address for example R1 g0/0 192.168.1.2 and R2 g0/0 192.168.1.3 or we are oki only with Virtual IP address?
One command that I have hard time to understand is the "Preemt' in HSRP...that's is mean that if configure in the Active Router it keeps the Active even if the interface fails...? Please Dan or somebody....?
this means if the active router falls and the standby switches to active, once the active router returns back to normal the connection will switch back again to the active router
hi when i do the config of hsrp using your senario i diconnect the g0/0 on r1 but it still is the active router could you tell me the reason why. also, i have enabled the command standby track g0/1 thankyou
the standby group configuration on R1 was wrong at the track line parameter, it was configured as group 0 instead of 1, that`s why the R2 was not in active mode, whats weird is how could you ping outside! :/ Thanks for the classes :)
d0tnix The reason the ping was successful is because it actually went PC-A -> R1 -> R2 ->. Initial frame had D MAC = 0000.0C9F.F001 (0000.0C - Cisco ID, 9FF - HSRPv2 ID, 001 - group #), so according to S1's CAM table, the frame went to the HSRP Active router first (R1). R1 knows about the 209.165.200.14 host from OSPF adjacency on its g0/0, so the next frame has D MAC = R2's g0/0.
Doesn't work. Did exactly pin point the same as Dan did. Using Packet Tracer 7.2.1. Gateway did not change in PC and it does not reach Edge Router when cutting off cable to R1.
Something is wrong with this Lab. It does not work as expected. You are not going through router 2 when you said "Its obviously going through R2" Instead the PC is going 192.168.1.1 -> back down the LAN with R1 OSPF route to R2 Try disabling the OSPF on R1 and try pinging again, NO GO There is something wrong with the TRACK COMMAND in packet tracer. When i disconnect G0/1 nothing happens and R1 still thinks he is the Active router.
While configuring standby priority on routers make sure difference is only 5, means on R1 if priority is 95 then on Active Router R2 it should be 100 because "standby track interface" command will decrease the priority of Router by 10 when interface goes down. If you configure priority values as R1(95) & R2(120) it wont work when track configured interface goes down. because 120 - 10 = 110 still has R2 has higher priority then R1.
I'm still a beginner . I think that a Preempt on R2 will only be necessary if it has to compete with another router for the Active position. however, your suggestion is good practice.
Your "TRACKING" of G0/1 DID NOT WORK... Because you forgot to input the number of the standby group in your command. Upon your SHOW RUN we can plainly see that your omittance… Resulted in a "Standby 0" statement... And so would NOT affect the Standby 1 group.
Isn't there a mistake in your TRACK statement !? You didn't specify STANDBY 1 TRACK..... But only STANDBY TRACK without the ONE.... Which the IOS in your SHOW RUN translated into the command STANDBY 0 TRACK! Seems to works still... But God only knows why!

I passed the CCNA and I would like to thank you for your videos. They were a big reason why I passed.
Congratulations! I really appreciate hearing that. It takes a lot of studying, so great job putting in the work!
I passed my ICND1 and now I'm studying for ICND2. Thank you so much for these labs and explanations.
Op io p ppo
Taking ICND2 Jan 31st. If I pass, I owe danscourses big time! Even if I fail and retake, I still have learned so much from this channel.
The preempt command was left off of R2, which is why you weren't seeing HSRP failover to R2 when S1/0 was brought down on R1. The rest of the lab is great. Thanks for the video.
yes you are correct. preempt must be on on R2. because Preempt is used to identify who is who.
Congratulations for your lesson on HSRP but especially for the pronunciation of your English, understandable even for those who are not native speakers. Thank you very much.
Thank you so much Dan for preparing quality labs. I am CCNA certified and your work really helps me stay up to date with my skills.
Dan the friggin man to the rescue.
I've been stubbornly going at this solo for 2 hrs now, trying to complete a homework assignment. Thanks so much for taking the time to create such helpful and quality videos.

Thank you .. I had a two hours course to watch on the same matter
You explained it to me in 10 minutes
Keep up the good work
Your voice are simply amazing, everything going to my ears like a charm! Thank you teacher!
I'm assuming the standby group number doesn't matter as long as it's the same for both routers?
Nicely done.....Thank you from Nepal Asia.
You are such an awesome teacher with fantastic explanation.
Hello Dan, I've noticed that you have a mistake in configuration on from R1, you typed standby track G0/1 wich will by default set HSRP group 0 for that particular command. The correct way is to specify the group for that command and optional the decrement value

Thank you Sir
I have made Lab like you with Ripv2 and HSRP work good...
Your tutorial is BEST as BEST
Thank U once again for Lesson ...
Best teaching ever!!! Could you please make a video of VRRP and GLBP too...
nice simple topology to learn HSRP... thanks mate
Hi Dan...thanks a lot..You haven't discuss the ospf side of this video?
Love your videos. Very good quality teaching...
do you have a full video of this?
Got the lab file - thank you for the lesson Sir!
doing a tracert on the pc to the isp will also let you know which router its using to get to the destination.
Pretty decent explanation.
Thank you!
Great teacher!
I hope this message gets to you...How did you configure the ISP? Thanks for all your teaching!!!
Hello mister, can that cable between the routers(those that have holes in between) be a serial cable the red one ? and if so, will the hsrp still work?

Thanks for the video, unfortunately, i can't download the file, is there another location where I can get it?
thank you you exainled very well
So we don't need preempt and track command on R2?
At 14:21min you can see that the tracking id is different from the rest. The tracking id is 0 instead of 1, is that correct? Would that be the reason why the standby router did not show the status change messege?

well only you got it man.
Awesome..Explained very Clearly..
Dan this helped a lot . thank you
If you are running multiple VLANS into the routers using HSRP, you do the same commands except for configuring the virtual IP , am I correct ?
hmm how is this HSRP, if the edge router is down. All networks are down?
Hi dan can you make a video regarding HSRP in Multiple Vlan?
please I really need to know how it going to be configured.
And by the way our team would like to thank you for the
generosity you have in sharing some of your knowledge in Cisco.

I cannot open the zip file. My version is 8.0.Must I downgrade to version 6.1 in order to open the file?
Thank you so much for not locking the move devices function Dan!,
it is really annoying when I do the Cisco PKA and cannot move the objects!
hi dan, does it work without edge router? I have 2 router with different 2 isp provider and I want to run it with redundant internet connection. any inputs? thanks!
I happily confirm in this way that the activity mentioned in the begining of this video works with Packet Tracer 7.2.1 too.
doesnt work
@@ClaytonXL1 You have different version 7.2.1* after the * propably.
Dan I'm curious about your ISP-A configuration. Could you talk a bit about how you made it. I don't seem to be able to run your download even though im using 6.1. I was hoping to recreate this. Thanks.
I´m not able to download the activity on your website.
it s very useful. tnx for the labs ..

why do you use crossover cables to connect router to edge router. shouldn't it use a DTE/DCE???
hi!

No load balancing with HSRP. You need to use GLBP to load balance. But if you have multiple VLANs (IP subnet) you can distribute them on the two routers.

Hi Dan, thanks for this video very informative as well.
could you share name of application which you use to record ur videos?
ala bagazi Camtasia
Nice one!!
Thanks You Mr. Dan for website with zipfiles. :) It's realy helpful
how can I create isp-A cloud?
Why track g0/1 instead of g0/0?
Great tutorial ❤️
Why are you using ping when you can see this so much better with the tracert command from the host?
hello from Tajikistan i have a problem i setting HSRP and i wont to reconnection my routers in real routers cisco
thank you very much for the explications and your magnifique website
I'm unable to download the file
can you please let me know how you add two routers on a cloud
One command that I have hard time to understand is the "Preemt' in HSRP...that's is mean that if configure in the Active Router it keeps the Active even if the interface fails...? Please Dan or somebody....?
this means if the active router falls and the standby switches to active, once the active router returns back to normal the connection will switch back again to the active router
Thanks Keiotic
hi when i do the config of hsrp using your senario i diconnect the g0/0 on r1 but it still is the active router could you tell me the reason why. also, i have enabled the command standby track g0/1
thankyou
Is hsrp a routing protocol ?
@
Hot Standby "Routing Protocol"
the standby group configuration on R1 was wrong at the track line parameter, it was configured as group 0 instead of 1, that`s why the R2 was not in active mode, whats weird is how could you ping outside! :/
Thanks for the classes :)
***** using the 6.1 version, i wasnt able to open it. have no idea whats the right version to use.
d0tnix The reason the ping was successful is because it actually went PC-A -> R1 -> R2 ->. Initial frame had D MAC = 0000.0C9F.F001 (0000.0C - Cisco ID, 9FF - HSRPv2 ID, 001 - group #), so according to S1's CAM table, the frame went to the HSRP Active router first (R1). R1 knows about the 209.165.200.14 host from OSPF adjacency on its g0/0, so the next frame has D MAC = R2's g0/0.
Doesn't work. Did exactly pin point the same as Dan did. Using Packet Tracer 7.2.1. Gateway did not change in PC and it does not reach Edge Router when cutting off cable to R1.
Very interesting
Excelente !
How to use HSRP with subinterfaces?
When interface G0/1 of R1 fails , PC can't ping ISP-A . Why?
Excellent, thanks for share.
Can I get the packet tracer file
amazing job !!
What config did you do to s1 to s2 to connect they cant seem to talk to each other with a straight through cable
they are like devices so you use crossover to connect them.
but those switches are connected by a straight through in the video
have you tried changing the cable to crossover to maybe see if ur issue will be sorted?
Yes I know switches will connect with a cross over cable I'm just curious about the video and how he used straight through
ooh okay if i find out will let u know :)
how u assign ip address into the cloud(ISP)
AWESOME!
Cheers!
Dan CHEERS'd me! haha YES!!!!!
I am having unstable state in hsrp
Sir link 🔗is not working
Sweet - thanks
Am i the only one who cant access Dan's website?
THANKS MEN
Something is wrong with this Lab. It does not work as expected.
You are not going through router 2 when you said "Its obviously going through R2"
Instead the PC is going 192.168.1.1 -> back down the LAN with R1 OSPF route to R2
Try disabling the OSPF on R1 and try pinging again, NO GO

If you configure priority values as R1(95) & R2(120) it wont work when track configured interface goes down. because 120 - 10 = 110 still has R2 has higher priority then R1.
but i m working pt 7.0
thanks sir
and i think you should also use the preempt command on R2
I'm still a beginner . I think that a Preempt on R2 will only be necessary if it has to compete with another router for the Active position. however, your suggestion is good practice.
u ar right buddy
Your "TRACKING" of G0/1 DID NOT WORK...
Because you forgot to input the number of the standby group in your command.
Upon your SHOW RUN we can plainly see that your omittance…
Resulted in a "Standby 0" statement...
And so would NOT affect the Standby 1 group.
why is my standby track g0/1 is not responding? PC-A says destination host unreachable when the g0/1 in R1 is down. anyone can help me?
Enable preempt on R2. That will resolve your issue hopefully.
i love to break stuff....i removed R1 all together and......
Isn't there a mistake in your TRACK statement !?
You didn't specify STANDBY 1 TRACK..... But only STANDBY TRACK without the ONE....
Which the IOS in your SHOW RUN translated into the command STANDBY 0 TRACK!
Seems to works still... But God only knows why!
wow :D
thanks bro
fucking everything works in theory, when it comes to reality everything just starts acting weird
Thanks alot
