C1 and C2 just use their global routing table. P1 and P2 have two VRF's, customer and backbone. I have the C1 and C2 connections tagged in the customer VRF and the P1 to P2 connection in the backbone VRF. Is there any way to distribute the customer vrf table between C1 and C2 without having the backbone routes including while being limited to just using route-targets? What is the best way to accomplish this goal?
