I ran into this same thing with our core 3750G here at work. IPv6 was really only supported on Adv IP Services prior to 12.2(50)SE. Here is a snippet from the 12.2(50) release notes:
These IPv6 features are now supported in the IP services and IP base software images: Feature Releases Earlier Than Cisco IOS Release 12.2(50)SE Cisco IOS Release 12.2(50)SE and Later Access control lists (ACLs) Advanced IP services IP base DHCP for IPv6 (DHCPv6) for the DCHP server, client, and relay device Advanced IP services IP base Enhanced Interior Gateway Routing Protocol for IPv6 (EIGRPv6) Advanced IP services IP services Hot Standby Router Protocol for IPv6 (HSRPv6) Advanced IP services IP services Open Shortest Path First Version 3 (OSPFv3) Advanced IP services IP services Routing Information Protocol (RIP) Advanced IP services IP base Static routes Advanced IP services IP base We had 12.2(46) and I couldn't figure out why I didn't seem to have the "ipv6 unicast-routing" command even after the sdm profile change and reboot. Update to 12.2(50)SE or later. On Wed, May 4, 2011 at 9:53 PM, Lemish, Christopher < [email protected]> wrote: > Guys, > > I ran "sdm prefer dual-ipv4-and-ipv6 def" on my Cat2/3 and reloaded.
