Arg, totally forgot: there is bug CSCuf86015 for 4.3.1 - no known Fixed
releases?  (Don't now if this applies for asr9001)
If nobody knows a release were this is solved I'll reopen the old TAC case.

-> For IPv6 flows AS numbers are 0 for prefixes learned via directly
connected ebgpv6 neighbors.
(The bug report is a bit more specific, so that we could thought that it
does not apply for us, but it did.)

One workaround is to set the nexthop to the neighbor's global IPv6
address, e.g.

route-policy peer-in
  ...
  set next-hop peer-address
end-policy

Obviously, don't do that for route-servers at IXPs...

This works for us with Typhoon line-cards, ASR 90(06|10), RSP-4G and
4.3.1 running.
