Does anyone have any experiences with the Cisco IPv6 IOS (T or S releases)? Can be either good or bad experiences. I heard there were some issues (router freezes etc) with the T releases...
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. Michel.
