I need to create a router that will make ipv6 available to downstream users if it is available.
I have encountered two problems using the "naive" approach:
1) I am receiving a /64 address from upstream via radvd. When I turn radvd on on the router, the network becomes unreachable. (I'm also not sure what address to specify.)
2) In general, given the fact that there may be multiple routers on the same network, I'm not sure what kind of address to specify in order to ensure uniqueness down the line.
I'm doing this all in Debian (actually, the pilot version is in Etch for reasons we need not go into).
