You must have missed my post asking people to be clear in their distinction between RA and SLAAC.
I will re-cap: - RA does NOT give your host IPv6 addressing information.- SLAAC gives your host IPv6 addressing information. SLAAC data is carried in RA messages, as an OPTION.
- Another RA OPTION is "use DHCPv6 to get addressing information".DHCPv6 can operate without RA now. You can send DHCPv6 requests to your local LAN before you get an RA message telling you to do so. This requires you to manually configure your host to do that. That sounds like a waste of time, when you can use RA messages to tell your hosts to use DHCPv6 to get addressing information. Of course, you DHCPv6 does not currently have an option for default router, so your need RA for that. Again, RA is not giving out addressing information, only "Hi, I am a router".
I suspect this removes the desire for getting "VRRP" without RA as well for those of you wanting to use DHCPv6 for addressing - RA is not giving out addressing information, and is only giving out "Use DHCPv6" bits and a router address.
