Hello misc, I'm starting to play around with IPv6 and rad(8). I've noticed that I can broadcast arbitrary prefixes via "no auto prefix" combined with "prefix <prefix>". These get assigned properly via slaac and can be used to forward packets, but if I don't assign an IP in the prefix on the broadcasting interface the return packets won't get delivered, because that interface doesn't participate in the ND process for that prefix.
>From what I gathered RA (and thus the default gateway on the slaac nodes using them) is always the link-local address. If I don't have a need for a public IPv6 address on my router: 1) Is there a requirement I overlooked to have the public IP on the interface? 2) If there is no such requirement, is there a requirement to not do ND for not locally assigned prefixes? 3) If there is no such requirement, did I miss a switch to enable ND for a non-local assigned prefix? Or is there a reason to not have one? martijn@
