[Olsr-users] Heads-up: AHCP redesign

IPv6 stateless autoconf has two parts: configuring link-local addresses,
and configuring global ones.

Link-local autoconf does indeed work in mesh networks.  Configuring global
unicast addresses, on the other hand, requires receiving a router
advertisement, which doesn't work in mesh networks.

Babel has been using link-local addresses for routing since the beginning,
and hence a Babel node is able to route IPv6 even when it has not been
configured (a pretty cool feature of IPv6, if you ask me).  However, such
a Babel node can only route other nodes' addresses and originate link-local
packets -- it cannot originate global packets, since it doesn't have an
address it could use as the source IP.
