I just upgraded our border routers from CHRs on v6 to 2216's on v7.9. We have 2 border routers, each connected to a single upstream ISP and an iBGP peer between them. Everything seems to be working fine except routes are not being advertised from 1 of the border routers to the other. One router is advertising to the 2nd, but the second is not advertising back to the 1st. The connection/peer config is the same for both.

Do I need to enable client-client reflection on one? I didn't think so, and it was not enabled with v6.
