As long as you don't change your MAC address you'll get the same IPv6 address every time, this works fine for servers unless you need a memorable address. BTW, I don't know anyone who uses DHCP for their servers.Hopefully vrrpv6 will work with RA turned completely off.With router advertisements present you don't need VRRP because you have dead neighbor detection.
And that helps the hosts on the same l2 segment that need different gateways how? Or hosts with access to multiple l2 segments with different gateways?RA is a shotgun. All hosts on a segment get the same gateway. I have no idea what a host on multiple segments with different gateways would do. Hosting environments can get complex thanks to customer
requirements and baggage from previous migrations. Load balancer and VPN configurations are common culprits but there are also cases where servers need different gateways for routing policy reasons. All of this is easily accommodated with static gateways and the redundancy provided by vrrpv4. Please don't take that away from us. Migration to v6 will be difficult enough without subtracting functionality from our existing tools. Other than that I look forward to seeing what wonderful things we can do with RA to simplify things in cases where shotgun == ok. - Kevin
