I was looking for information on running IPv6 in VRF on the Catalyst 3k platform and there wasn’t much information available. I tried running IPv6 in VRF on Catalyst 3560 with correct SDM profile but got this error message:
IPv6 VRF not supported for this platform or this template
I checked with Cisco and you need to have Catalyst 3560-X/3750-X with release 15.2(1)E for IPv6 to be supported in a VRF. This means the feature is not supported on the non X models.
The feature is also available on the 3650/3850 platform with IOS-XE 3.6.0E.
I hope this information helps someone looking for IPv6 support in VRF.
