I don't know what I was thinking last night, but I believe I had SLAAC +
DHCPv6-PD working myself, but wasn't satisfied. =) I'm not comfortable
using SLAAC for WAN addresses in a service provider environment.
I do DHCPv4 relay today. DHCPv6 relay worked perfectly on an PVI, but with
a SVI with it was very much hit and miss, such that now CSCtl77398 has been
created. Enabling "ipv6 multicast-routing" has dramatically improved the
success of DHCPv6 relay. So while the bug is not fixed, it's good enough
that I can continue with preparing for a trial.

Haven't had the chance to look at that one. Will check it out.

It had better be, as IOS 12.2 SRE only supports SLAAC + DHCPv6-PD. Most
of the Cisco documentation I've seen, says that is their beautiful
layout. No more proxyarp/nd. Instead, assign a /64 to each subinterface,
perform SLAAC, then hand out prefixes via DHCPv6-PD if someone needs a
prefix.

Yeah, I could see the forwarding code supporting it. Cisco documentation
stated proxynd with rbe/unnumbered vlans isn't what they support. How
did your tests go mirroring the v4 method using dhcp forwarding with the
v6 method?
