VRF-lite Configuration

[@pradeepchandran9920]

I must have to say this is the first time i am seeing the concept of VRF this simple and easy to understand. Thanks a lot

[@szabi0112]

If everything were as easy in my life as this, I would be President of the United States. Thank you very much for the video. It is the most rewarding experience for me today.

[@aur3nnnn]

This is a life saver, I just started working for an ISP a few days ago and my CCNA definitelly didn't cover anything about VRF combined with OSPF so this will definitelly help me to be at least aware on how to do a basic configuration.

[@172Break]

Tell your ISP employer to ditch the OSPF and use IS-IS!

[@scorpio_1312]

This answered the question I had for weeks. Very well explained and easy to understand. From now is just a matter of practice, practice to master this topic.

[@phantomwhisper519]

Thank you, it was so helpful! One of the bests! The steps are professionally explained, all clear, and the video is worth gold.

[@srb1855]

Guys - fantastic demo!! I replicated this topology in CML with a few modifications - mainly two OSPF areas just to observe the LSDB behavior. Very very helpful to clear up the F.U.D. as Kevin would say....😉

[@Simon-bv7mj]

Incredible explanation, very easy to understand.

[@mahendrakumarsahu4395]

So simple and so clear !!!
I loved the video .
It made my vrf concept cristal and clear.
Glad to you Kevin 💐 🙏🙏🙏🙏🙏💐

[@MrWinfil]

[@mouvratha]

Simple explained easy to understanding, Thank you man

[@bountifulish]

Sir, thanks a lot, you saved 2 hours of my time with your prompt and precise explanation. Always your fan.

[@robinkhn2547]

Perfectly explained. Helps me writing my fundamentals part for my Bachelor-Thesis.

[@michaeldanquah9309]

very well done CJ. I recently had to implement a NAT statement on vrf and had a litttle difficulty finding where to reference the specific vrf, its done towards the end.

[@mips-m]

This is great for customer traffic separation, but what if you need to access something in another VRF? Maybe customers need access to Internet? Or maybe access to common servers in DC? Only way I found is VRF route leaking. It would be nice to demo that concept.

[@chrisglesner]

Excellent video! Thank you for the tutorial, Charles.

[@krishnendubiswas5560]

Crystal clear explanation. Thanks a ton.

[@tinashemadangure8140]

Great stuff as l start my ISP journey.

[@Pawilson68]

love this video. Just have one question. Why didn't you choose the encapsulation on the int gi0/0.1 to dot1q 1? to make it easier to correlate it with the sub int?

[@hcetc]

Wonderfully explained and demonstrated. Thanks a lot!

[@rogersblog2562]

well explained charles

FOOOFIGTA!!!! Love the video, many thanks!

[@tpa6laf]

Great video

[@corelinksonline9304]

wow great sir

[@kishinasura1504]

Thank you. Do you know how to configure authentication for VRF?

[@sanjedgaming8124]

Can we use PE to Customer CE BGP instead of OSPF ? because sometime use need internet also via same link.

[@sonnyyombo2230]

Thank you

[@jamviator]

Question... why didn't you use the "vrf definition" command or the "address-family" command?
When are those commands needed?

[@samsampier7147]

Great video. Charles not matching the sub interface id (.1) to the dot1q tag (2) makes me uncomfortable. I know it's completely arbitrary and does not need to match.

[@sheryarsaqib55]

Very useful content...

[@caferhakanadar]

Thanks, i did understand

[@okochat]

Am confused, Help Please!!
How come Router 3 can see all the other routes in the global routing table?
I thought the ospfs were only vrf advertised? how come they appear in the global table too?

[@syedshohidahmed9880]

Hi, thank you for the video, how come we don't use area 0 when configuring OSPF?

[@robinkhn2547]

I was wondering the same thing, I always thought that having an area 0 is mandatory since it defines the Backbone Area.

[@geodarwin]

@@robinkhn2547 if there is more than one area then area 0 presence warranted

[@yilmazurgun]

Great video!

[@dameonpryce9931]

Very informative! Thank you!!

[@Officialprincepandey]

Thanku so much ......Very important

[@SaSemairesearch]

Perfect!!

[@scorpio_1312]

I was thinking, what would it happen if instead of a point-to-point link between R1 and R2, I had a Port-channel, how things would change in that scenario?

[@cyberciscowebdev8371]

I am curious why area 1 was used in ospf and not area 0? Is it because they are customers and not part of the service provider's backbone area?

[@maxnoob1982]

can you upload the configuration text ???

[@hatemnegm2688]

Perfection

[@nzangba1]

Wow, So vrf is like Vlan of layer 3

[@fayassalam1199]

I am a Beginner in Networking..Could some one explain why we used encapsulation .1q in the R1 g0/0.1
and g0/0.2 interfaces?

[@okochat]

Because to use an interface with vrf it has to be encapsulated(basically divided virtually)
We cant the normal gi0/0 as they physical interfaces which would belong to the global table
One physical interface can only be set one ip unless encapsulated into virtual/sub interfaces

[@liadedri6165]

did someone wroth all the commands and have them as a script? and if so please sand (:

[@virtualvnet8737]

Why use AREA 1 ospf and not area 0 , I know is Mandatory area 0

[@EAleg]

You can use 2, 3, 5, 10. does not matter. why not 0, maybe because usually this is back-bone area)

[@okochat]

Any numbering is fine
