RA and VRRP are not mutually exclusive. What you can=92t have =
(currently) is routing information distributed by a DHCP server which =
may or may not actually know anything about the routing environment to =
which it is sending such information.

There=92s no problem doing this in IPv6. You can easily statically =
address a system and you can easily turn off privacy addresses. You can =
even do that and still get your default router via RA or you can =
statically configure the default router address.

As such, can someone please explain what is the actual missing or =
problematic requirement for the corporate world?
