Pardon the top post, but I really don't have anything to comment below other than to agree with Chris and say rfc5963 is broken. NEVER EVER EVER put an IX prefix into BGP, IGP, or even static route. An IXP LAN should not be reachable from any device not directly attached to that LAN. Period. Doing so endangers your peers & the IX itself. It is on the order of not implementing BCP38, except no one has the (lame, ridiculous, idiotic, and pure cost-shifting BS) excuse that they "can't" do this. -- TTFN, patrick On Jan 14, 2014, at 21:22 , Christopher Morrow <morrowc.lists () gmail com> wrote:

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 fabric4. 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
