I've got two sites in the US (different states) with BGP peering to different ISPs with our same AS. Both advertise different chunks of one of our /20's.
Site A gets full tables, site B just a default route (although this may change at some point).
Site A won't install any routes from Site B (via the internet) because it sees it's own AS in the path (this is expected).
I'm curious what people prefer in this situation. "allowas-in"? iBGP between my edge routers via the internet? Something else?
