VRF-lite Configuration
HTML-код
- Опубликовано: 11 мар 2021
- In this video, Charles takes a look at the configuration of VRF-lite. VRF stands for virtual routing and forwarding, or sometimes we see that called VPN routing and forwarding. This is a technology which allows us to create multiple routing tables within a router rather than having a single, global routing table.

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
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.
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.
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.
Tell your ISP employer to ditch the OSPF and use IS-IS!
So simple and so clear !!!
I loved the video .
It made my vrf concept cristal and clear.
Glad to you Kevin 💐 🙏🙏🙏🙏🙏💐
Rien à dire @Kevin . Bravo . et merci pour tes efforts.
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.
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....😉
Sir, thanks a lot, you saved 2 hours of my time with your prompt and precise explanation. Always your fan.
Thank you, it was so helpful! One of the bests! The steps are professionally explained, all clear, and the video is worth gold.
Perfectly explained. Helps me writing my fundamentals part for my Bachelor-Thesis.
Cheers Kevin. Well explained and very much appreciated :)
Wonderfully explained and demonstrated. Thanks a lot!
Excellent video! Thank you for the tutorial, Charles.
Crystal clear explanation. Thanks a ton.
Simple explained easy to understanding, Thank you man
best tutorial ever....great work sir!!!
Incredible explanation, very easy to understand.
Excellent video, very informative.
Excellent explanation. Thanks
Thank you for this great video!
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.
Very well articulated.
Very informative! Thank you!!
Thanks, Charles for this informative video lecture on VRF-Lite, i have learned even i am a newbie. ---CCNA 200-301 Master Class student of Kevin Wallace
Great stuff as l start my ISP journey.
Great video!
well explained charles
well explained and.. I really like your poster!!! 😄
Thanku so much ......Very important
Great video
Well explained.
Very useful content...
Nice explanation
FOOOFIGTA!!!! Love the video, many thanks!
wow great sir
Thank you. Do you know how to configure authentication for VRF?
Perfection
Thanks, i did understand
Thank you
Can we use PE to Customer CE BGP instead of OSPF ? because sometime use need internet also via same link.
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?
Hi, thank you for the video, how come we don't use area 0 when configuring OSPF?
I was wondering the same thing, I always thought that having an area 0 is mandatory since it defines the Backbone Area.
@@robinkhn2547 if there is more than one area then area 0 presence warranted
Question... why didn't you use the "vrf definition" command or the "address-family" command?
When are those commands needed?
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?
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.
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?
can you upload the configuration text ???
Wow, So vrf is like Vlan of layer 3
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?
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
did someone wroth all the commands and have them as a script? and if so please sand (:
Why use AREA 1 ospf and not area 0 , I know is Mandatory area 0
You can use 2, 3, 5, 10. does not matter. why not 0, maybe because usually this is back-bone area)
Any numbering is fine
