Leak Routes Between VRF's

Leak Routes Between Routing Tables | VRF's Part 4

We've been very successful in keeping customer routes separate with VRF's. We've even extended this across the core using route-targets, route-distinguishers, and MPLS.

What would happen now if we wanted to share some of our routes with our customers?

This is called route leaking, which we can achieve once again with MP-BGP.

There are a few challenges along the way. What if we want to share all routes in a VRF? What if we want to be selective? And how do we prevent customers from advertising rogue routes?

In this video, we'll see how to configure route leaking and export maps to to share routes between VRFs.

This includes a lab you can follow along with.

You can download the labs, and practice on your own if you want (Patreon).

Part 1: VRF Lite - The Fundamentals of how VRF's work. This covers route separation, why you need it, and how it's configured

Part 2: Dynamic Routing - Taking it a step further, we see how to add OSPF, EIGRP, and BGP routing, all while keeping it VRF-aware

Part 3: Route Targets - VRF's are local to each router. But, we can use route-targets and MP-BGP to share routes between VRF's on different routers. The ed result? VRF's are spanned across your network!

Part 4: Route Leaking - VRF's keep routes separate, but what if you have some important services to share? How do you share the routes then? With Route Leaking!

Your calm and steady voice, this is what makes me absorb the content much efficiently.

Thanks again for another great video, I again had some configuration I needed to work through, with a customer now requiring some shared service access, read a lot of documents in vrf route leaking and got 95% of the way there but your video again helped me put the final puzzle piece together and connectivity is now working at least in my lab. I'm glad I immediately thought of your videos when I got stuck and checked if you made one

[gastonhitw]

wow I managed to get it working on a much bigger lab, I have never used vrf and I'm thrilled that I could follow this through and not make a single mistake, I need to document myself much more on vrf tho

[LuisReyes-mwjo]

Great, everything I needed to know about VRF! Thanks

[purplemonkeydishwasher]

lovely video. well thought out and builds nicely on the concept

[xguidosan]

short and solid explanation, thank you!

[theleftfoot]

Superb! With your Vids i've done my SMB LAb...cheers!

Great, I love this channel in this video I can learn about share the common route to each customer and filtering route from customer.
finally I understand that unable to solve the route overlapping, 10.10.0.0/24.

[hazemshoep]

thanks for your informative videos.. one question please.. If I get the Patreon accout, will I be able to see all the website content or just this lab file?

[goncalocontente]

Great videos. You could extends the subject and do some MPLS videos

[wimvs]

Thanks for the video. Is there also a way in similar setup where you can leak from and to GRT?

[PowerUsr]

In Juniper this is basically L3VPN so I assume this is the case in Cisco.
Any plans on how to route leak using virtual router instance

If you were to export a default-route from Shared Services into the Cust VRFs would this allow CustA and B to speak via the Shared Service VRF? How do you deal with importing a default?

[BillyBufter]

How do you find VIRL? Also, what material would you recommend for studying VRF/MPLS? Thanks for the vid. BB

[krisdrk]

The ping to 192.168.10.1 is not working from CustA-R1, export and import are is fine as i can see routes on both VRFs. Debug ip packet gives "FIBipv4-packet-proc: packet routing failed" on CORE-1, Any ideas?

[disney.here.we.go]

Which terminal software and platform are using to create the lab?? Please keep it up! Good job!

[ПеткоКондев]

Good videos. Thank you for providing these. I only wish you would go a little slower on the command line.

[rameshtekale]

Great Video Sir 👍 Please make more video on firewalls like check point
