Hello, Does anybody know if sup32/PFC3B support hardware forwarding of ipv6 over GRE or ipv6ip tunnels? IOS 12.2(33)SXH4. I can't find a definitive answer in cisco doc. I know "tunnel mode gre" runs in hardware, but I'm not sure if ipv6 on top of it will make any difference. Has anybody tried it? Thank you, Michael
