So this morning, I have been trying to configure IPv6 upon my network using the guide I found on reddit (of all places) at http://ipv6friday.org/blog/2012/06/ipv6-enabling-training/. Now at first glance, this appears to be working, however, the machine that I am testing, while it is correctly obtaining an address from the range, isn't routing IPv6 where I would expect as demo'd by:
[server] output of "ping6 -c 3 www.facebook.com"

and
[client] output of "ping6 -c 3 www.facebook.com"

A copy of relevant configurations is below. I have partially anonymised the ranges used:
[server] /etc/radvd.conf
interface eth0 {
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvHomeAgentFlag off;
prefix 2a01:348:6:XXX::/64 {
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
};
RDNSS 2a01:348:6:XXX::2 {
AdvRDNSSLifetime 30;
};
};
[client] output of "sudo ifconfig"

[client] output of "ip -6 route show dev wlan0"
2a01:348:6:XXX::/64 proto kernel metric 256 expires 86405sec
fe80::/64 proto kernel metric 256
default via fe80::202:XXX:XXX:7345 proto kernel metric 1024 hoplimit 64
Now by my thinking, this is trying to route IPv6 over loopback by default and not using the other route via 2a01. My question, what is going on here and how do I change the default routing?
Thanks in advance!
Edit
As requested, a traceroute from the server to facebook:
