In your previous mail you wrote:
Is there a spec for what a PPP connection is supposed to do once the
link-local addresses are established? Shouldn't the "client" at that
point perform a router solicitation to determine the prefix on its
endpoint or something?
=> there are three cases:
- both ends are hosts: nothing to do.
- one end is a host, the other one is a route: the host sends router
solicitations, the router sends router advertisements, and when
the host receives a router advertisement it applies RFC 2462
(auto-configuration) and can get global addresses.
- both ends are routers: a routing protocol should be started
(look at Itojun's dialup draft for other details).
PS: in the common case (router-host) the router uses a static config
(in the ipv6-up script) and the host auto-conf/neighbor discovery.
This works well for a /128 if the implementation is good but Itojun
has good arguments about what to do further (so read his draft).
