that only works in IPv4 if you have a good tail wind and your fingers crossed. > As the home router shouldn't do PD to further distribute the ISP-prefix it is > hard to support this with IPv6 except with detecting the case and doing > NDP-Proxying then as bridging might not always be possible or desired in this > case. you could use hierarchical PD, just that it doesn't work well with: - networks with loops - multi-homed networks and it is quite wasteful with regards to subnet space. > And supporting all of this above would have the side-effect that such ISP > without PD would be supported as well so I'm not really sure. ND proxy fails in any topology with a loop. we do have an implementation on github that implements http://datatracker.ietf.org/doc/draft-arkko-homenet-prefix-assignment/ that supports prefix assignment with an arbitrary topology in the network. why not use that? cheers, Ole _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
