good plan.
I see three options 1. redistribute into my igp (OSPF) 2. configure ibgp and route them within that infrastructure. All thedefault routes go out through the POPs so iBGP would see packets destined for the peering fabric and route it that-a-way3. leave it "as is", and let the outbound traffic go out my upstreams andthe inbound traffic come back through the peering fabric
4. all peering-fabric routes get next-hop-self on your peering router before going into ibgp... all the rest of your network sees your local loopback as nexthop and things just work.
Advantages and disadvantages, pros and cons? Recommendations?Experiences, good and bad?I have 5 POPs, 2 OSPF areas, and have not brought iBGP up between thePOPs yet. That's another issue completely from a planning perspective.thanks Erichttp://tools.ietf.org/html/rfc5963 I like no-export
