Re: ipv6 multicast address

Please see Section 13. The address to be used is FF02::12.

13.  IANA Considerations

   VRRP for IPv6 needs an IPv6 link-local scope multicast address
   assigned by the IANA for this specification.  The IPv6 multicast
   address should be of the following form:

      FF02:0:0:0:0:0:XXXX:XXXX

   The values assigned address should be entered into section 5.1.2.2.

   A convenient assignment of this link-local scope multicast would be:
      FF02:0:0:0:0:0:0:12
