VRF

First off, lets take a look at the topology I will be using for this example:

Everything works, and we the math is right, we should see an NHRP shortcut being created for the Spoke to Spoke tunnel:

In this post I will be showing you how its possible to use different paths between your PE routers on a per VRF basis.

This is very useful if you have customers you want to “steer” away from your normal traffic flow between PE routers.

In this post i would like to explain the usage of the “MPLS VPN Per VRF Label” feature.

By default, in each VRF, prefixes are assigned a VPN label, used to identify the route within the VRF itself.

This label is the only label that is being looked at by the receiving PE router.
