If you wanted, you could also look at doing each POP as a federation, which would get similar results as well. For egress traffic with different transit providers, you'll inevitably still leak some traffic between POP's with more-specifics learned via a single provider, but this should be small. An AS-prepend of non-local-prefixes would take care of ingress reasonably (again, expect some small surprises), though if you have the same provider to multiple POPs, you could also get there w/ just MED's. > My Cisco bookshelf isn't helping me much with this... Add Internet Routing Architectures to it then, it is well worth the read. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
