I have 6500E with Sup 2T, running the latest IOS 15.2.1SY1, I'm trying to configure ISIS IPv6 under VRF lite, but I'm getting an error message.
test(config-if)# ip router isis
%ISIS: Cannot enable ISIS-IP for process with mismatched vrf
test(config-if)# ipv6 address x.x.x.x.x
test(config-if)# ipv6 enable
test(config-if)# ipv6 router isis
%ISIS: Cannot enable ISIS-IPv6 for non-default VRF interface
test(config-if)# mpls mtu 9000
test(config-if)# mpls traffic-eng tunnels
test(config-if)# mpls ip
test(config-if)# isis ipv6 metric 4000
% ISIS IPv6 not supported on VRF interfaces
Is this feature supported in that IOS, the feature navigator is not helpful at all..
This link shows the support for 15M&T but not sure about the SY
