Catalyst 4507R SupIV                   cat4000-I9S-M      12.2(25)EWA11

Catalyst 2960G                              lanbasek9-m         12.2(44)SE

CBS3020                                        ipbase-m               12.2(50)SE3/12.2(58)SE1

C6509E/C4507R need static route/ospf/hsrp

Hi there,

According to the Cisco feature navigator: http://tools.cisco.com/ITDIT/CFN/jsp/by-feature-technology.jsp

HSRP support for IPv6 was introduced in 12.2.33-SXI1 (now deferred), so any of the current SKI or SKJ releases should be fine.

cheers,

Seb.
