Hi, I need some clarification as to what topology in which we can run OSPF with our customer inside VRF. I ran OSPF on one PE-CE link in area 6. I could only see in my VRF/OSPF table the intra-area routes and external routes that were injected by the CE router via redistribution. The CE router was also connected to other customer routers via area 0 and other areas. In PE's VRF/OSPF routing table, I could not see any inter-area route nor other external routes that other customer routers were injecting via redistribution although I could see them in my (PE router's) OSPF database. Funny thing is, when I removed VRF configuration and configured OSPF with the customer in the global routing table, I was able to see all routes getting installed in the routing table. Consulting a book, I hit across the following:
"When backbone areas are used within a VPN customer topology, the only caveat to be aware of is that any site configured to run an OSPF backbone area must be attached directly with the MPLS VPN Superbackbone, either through a direct link or a virtual link. This is mandatory because the PE routers always act as Area Border Routers (ABRs) and need to be able to exchange intra-area information with other ABR or backbone area routers." Does this mean that the PE always need connectivity to Area 0? Is there any way around? What am I missing?
