I am using VRF-lite (no MPLS) to isolate traffic between different parts of my network. Now however, I want to be able to somehow share or "leak" some routes between the different VRFs.
My goal is to allow some traffic to flow between the VRFs without having to connect to a separate physical router with some IGP, or without having to physically run a cable between two ports on the same router to connect the different VRFs together.
I am doing this on a 6509, so my concern with building some type of tunnel between the VRFs is that I do not want packets to be software switched if at all possible. What would be ideal is to share routes such that packets coming into the router in one VRF will be routed out via interfaces in the same or different VRFs by simply consulting the TCAMs for routing decisions.
The route target import and export syntax looks close to what I want to do, but I just do not know how to do all of this inside the one router.
Does anyone have any configuration examples that might be of assistance?
