2) What are the most common ways of managing the routing of delegated prefixes in the ISPs routing domain? Has a standard method/best practice emerged yet? Routing protocols? IPv6 RAs?
One obvious answer would be routing protocols. In my brief googling, I've seen a forum post that seems to indicate that Comcast makes use of RIPng on their CPE to propagate routing information for prefixes delegated to it. Can someone confirm this? This would seem as good a method as any to do this, albeit with obvious security concerns.
We've build a small tool which watches the dhcpd6 lease file for changes and injects the PD routes using exabgp (iBGP session with corresponding IA_NA address as next-hop for the IA_PD prefix). Best Regards, Frederik Kriewitz
