RE: Some comments on draft-ietf-vrrp-ipv6-spec-08.txt

Hi Steve,

This is regarding issue 1:

Rather than not running DAD, would the following achieve
the same effect?

The VRRP master does not respond to ND neighbor solicitation
for VRRP protected addresses if the source address is the
unspecified address (::). With this, when the address owner is
back up after being down, it will send a ND-NS for duplicate
address detection process. The current master would not respond.
Therefore, the IPv6 address will get installed and VRRP will
start. This will then make the current master to move to
standy state.

Does this make sense?
