Well, all looks well from what you've sent. The tcpdump shows the
router sending out the correct prefix (2001:8b0:13:1::/64) from a
link-local address (fe80::20c:29ff:fe57:23b6). Your client confirms
this ('received RA from fe80::20c:29ff:fe57:23b6 on pcn0'). It should
now configure the correct address 2001:8b0:13:1:20c:29ff:fecd:f77a/64
on pcn0. Are you sure that it hasn't done this ? Again, more details
(such as the output of `ifconfig pcn0` on the client) would be useful.

Remember, the client should already have a link-local address (see
previous mails I sent).
