Hi Santoshkumar,

Yes, it is possible indeed. The only prerequesite is that you enable HSRPv2 on the interface prior to enabling hsrp for v6. HSRPv2 does provide support for both v4 and v6.

Hi Santoshkumar,

It is indeed possible to have hsrp running for both ipv4 and ipv6 on the same SVI as I indicated previously. Here are links to configuration example.

HSRP for v6:

HSRP for v4:

Dear Ritter ,

           Yup i could see on below document .

https://supportforums.cisco.com/docs/DOC-16506

Q. On configuring an IPv6 HSRP standby group, run into an error message: "%FHRP group not consistent with already configured groups on the switch stack."

A. Only HSRP version 2 supports both IPv4 and IPv6. So configure "standby version 2" under interface.

I see the link is not SVI, how to configure VIP IPv6?

Thank you very much.
