IPV6 Support in Cisco IOS

[alicia.cliff]

I am having a difficult time determining why on a 2811 running IOS c2800nm-advsecurityk9-mz.150-1.M2.bin,  the router won't accept ipv6 commands.  The feature set from what I can discern includes ipv6 support. However, I have received mixed views.  Does advsecurity image support ipv6 or do I need adv ip services image?

Advanced IP Services and Advanced Enterprise Services packages should support IPV6

[Phillip Remaker]

The philosophical direction of Cisco is to have full IPv4 and IPv6  parity across feature sets.  Any IPv4 feature should appear in the same  license level of software for IPv6.

That said, some older software and platforms may have been missed.

See if the problem persists with the latest version.  If so, I'd treat it as a bug and open a case.
