Won't you still get loops or blackholes unless the eBGP routes on all border routers are identical?
As opposed to what, injecting the entire BGP table into your igp? That generally doesn't work well.
I think you also need iBGP speakers along all feasible paths between eBGP speakers.
I was assuming the eBGP speakers were directly connected over some sort of interconnecting backhaul. Again, you can't really figure out what someone's topology is from a short blurb on a mailing list. Yes, if there are intervening hops, they will need to speak iBGP as well and possibly configured as route reflectors if it isn't practical to fully mesh everything. Maybe there is a reason the legacy operator said both uplinks must be connected to the same router. If the two locations are not interconnected, that would be one reason. I don't believe the original poster described their internal connectivity. George
