Yes, it does. There was too much spam.....

This was discussed in the VRRP w.g. some time ago and there was a decision made to not have a dual protocol version of VRRP. Also, after rewriting it to use IPv6, I think having one document that describes both the IPv4 and IPv6 address resolution mechanism (i.e., ARP and ND) everywhere in the document would make the document very complicated and hard to understand. I think it is much simpler to keep the two separate. If VRRPv2 (for IPv4) needs to be revised in some incomparable way either a new message type could be used, or perhaps VRRPv4. The version and message types are four bits each. Not too likely we will run out soon. Also, VRRPv2 has been stable for a long while. Again please continue the discussion on the VRRP mailing list.
