So I could be way way off here so take with many grains of salt.
Can't speak for IPV6 but with V4 they use an A / B peering arrangement for customer links. Are you sure you're announcing your routes to the correct peer? If they do IPV6 with a single address then sorry for the misdirection but with IPV4 they definitely use a pair of sessions.

Subject: [c-nsp] IPv6 BGP on IOS-XR

Hi all,

Does anyone have any recommended reading for doing IPv6 BGP peering on
IOS-XR? We setup our peer with Cogent and can get full routes in, but can't
seem to figure out how to announce our /32. I had assumed it setup just the
same way as IPv4, but can't seem to get it to announce out. I did some
searching on Cisco's site, but didn't really find anything that pertained to
how/what to announce and what not to announce.

We are running version 4.0.1

Thanks,

Lee
