ipv6 on Cisco 2811

Unanswered Question
Oct 7th, 2009

Hi ,

Cisco Feature navigator says it supports IPv6 on following IOS & Model.

System image file is "flash:c2800nm-advsecurityk9-mz.124-15.T7.bin"

Cisco 2811 (revision 53.51) with 249856K/12288K bytes of memory.


i cannot run "ipv6 unicast-routing" command

also i am not able to assign ipv6 addresses to any of the interfaces. !!!

Anybody has any idea ? in fact it does not give me any ipv6 option from CLI ( neither privilege nor global config )

Also , can i run DHCP for IPv6 on Cisco 2811 router with above IOS ?

I have this problem too.

I just checked the Feature Navigator and it actually says that you either need ADVANCED ENTERPRISE SERVICES or ADVANCED IP SERVICES to run ipv6 on the 2811. ADVANCED SECURITY SERVICES will not do it.

12.2(10a) won't run it on a 2600 either?....
