VRF-Lite and BGP

acdixon9201

I'm hoping someone can give me some guidance on our possible design. We are going to be running a csr1000v as our edge router. We also are running BGP with 2 ISP's. I've been asked to create 2 vrf's, 1 for Inside and 1 for the Internet. The Inside vrf will hold our public IP block. I'm trying to get routing between the two vrf instances without running 2 copies of the Internet routing table. I've been setting this up in a lab, but cannot seem to get it to work correctly. I've leaked a default static route to the neighbors, but this seems to defeat the purpose of having the routing table in the Internet vrf. Can someone point me in the direction I need look for a solution? 


Thanks.

Hello

Not sure i understand you topology however having a vrf will produce two routing tables, one for the vrf and one for the global rib.

 

Now if your all you vrf next hop traffic is in the global rib then not sure what you trying to accomplish as you will also need static route on the edge rtr so it now knows how to return traffic into the vrf and as such anything outside the vrf would be able to reach it also.

 

Advanced apologies if I have mis-intepredted you question?

Hi Paul,
I'm including a drawing that might help to explain what I'm trying to accomplish. One of my goals is trying to keep from having the entire Internet routing table loaded into both vrf's.

Hi

I think for this you would need to create rout distinguishers for both vrf, use route targets to import/export

then you would redistribute bgp default but using a prefix list and route map to control the routes, you can also use export maps
