Someday Comcast will support native IPv6 where I'll be living, and I'd love to take advantage of it. I can't seem to figure out how I would set rtadvd and a DHCPv6 PD client up, though. I've posted on a few BSD forums, but they don't seem to have any information either.
My router currently is using DHCPv6 for some hosts, but has SLAAC configured (again, with rtadvd) for most. How would I go about getting DHCPv6 PD working in the future on OpenBSD?
I know this thread is over a year old now...but I too am wondering about essentially the same exact thing. I want to know if anyone has any information about how Comcast is implementing native dual stack on consumer cable connections. I know when you turn on IPv6 forwarding, that automatically disables ra_accept so that cannot be used on the WAN interface. But I hear like you mentioned that they plan to use DHCPv6 to give the customer the IPv6 address and some other info for a delegated subnet. Does OpenBSD 5.1 have a working DHCPv6 client/server?
