In my experience with 12.2(T) the issues were not related to IPv6; I
have been running it for two years for IPv6 peering.  V6 is now part of
12.3 (non-T) anyway. On mid-range platforms (72xx) the IPv6 performance
is sucky compared to IPv4 (which is why lots of people I know have
separate routers for v6) but on 25xx/26xx/36xx no difference.
