single interface multiple VRF

jahilnt10 · ‎10-04-2007

Is it Possible to have 2 or more VRF tables existing on one single Interface Eth/Serial. If the answer is yes, how do you guys do that.

It is certainly possible as long as you can configure the interface with logical subinterface such dot1q, frame-relay. Each subinterface would in turn fall into a specific VRF.

As harold pointed out, each logical interface can be a part of a different interface

It is not possible for a single interface though to be part of more than one VRF forwarding instance.

if you are just talking about route tables, you can always import the routes from another VRF which would be mean you have more than one routing table available :-)

Attched configs might help which i did in my lab

There are no P routers invoved in this as i had very limited routers available to test but it should be good to get a idea
