I'm assuming you've configured pcn0 with an IP address in this
network. In that case, can you try skipping the rtadvd.conf
configuration ? rtadvd should do the right thing (tm) when given an
interface on the commandline and that interface has an IP configured
(it'll do RA for the /64 it's been configured in).
See rtadvd.conf(5), especially this part :
As described in rtadvd(8), you do not have to set this configuration file
up at all, unless you need some special configurations. You may even
omit the file as a whole. In such cases, the rtadvd daemon will automat-
ically configure itself using default values specified in the specifica-
tion.
You've already been told to not use 4.2, you can even try ~4.4,
snapshots are currently pretty close to what eventually will be 4.4,
and there's been some changes to rtadvd which generally 'make sense'
(they're security related so won't fix your problem, but are good to
have nonetheless).

| Could anyone point me to where i'm going wrong?
Try giving a bit more information. What do you see when you tcpdump ?
What is the current configuration of the two interfaces (the one on
the rtadvd server and the one on the client) ? Who has this
2001:8b0:13:1::1 address ? I'm guessing it's the rtadvd server, but
you haven't told us.
