best practice for advertising peering fabric routes

[Eric A Louie <elouie () yahoo com>]

I have a connection to a peering fabric and I'm not distributing the peering fabric routes into my network.

I see three options
1. redistribute into my igp (OSPF)

2. configure ibgp and route them within that infrastructure.  All the default routes go out through the POPs so iBGP 
would see packets destined for the peering fabric and route it that-a-way

3. leave it "as is", and let the outbound traffic go out my upstreams and the inbound traffic come back through the 
peering fabric


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 the POPs yet.  That's another issue completely from a 
planning perspective.

thanks
