https://github.com/sbyx/odhcpd This is the only publicly available software, that can actually do full prefix sub-delegation. dibbler with radvd breaks, whenever a new prefix is advertised, because it only generates a new radvd config file without radvd actually picking it up. It’s also a mess to configure. odhcpd is used by OpenWRT, and solves this, by being both a router advertisement relay / daemon and a DHCP server. Such a solution is desperately needed for everyone who wants to actually migrate to IPv6 for real, but runs a server or a router behind a router on a typical SoHo ISP connection (where IP addresses/prefixes change at least once a day). Which is probably very common among typical Gentoo users. It is also vital, that this is included in the wiki article on setting up or migrating to IPv6. (I am willing to do that myself, if I had wiki access and the chance to set up odhcpd myself.) I am not able to write the ebuild and adapt the package to Gentoo customs though. This in where I’d need your help…
Here’s another case where this is required: http://webcache.googleusercontent.com/search?q=cache:http%3A%2F%2Fwww.hezmatt.org%2F~mpalmer%2Fblog%2F2014%2F11%2F20%2Fmulti-level-prefix-delegation-is-not-a-myth-ive-seen-it It also mentions another problem I forgot: Routing isn’t properly updated either. Something that odhcpd also solves, with icing on top.
