所以今天早上，我一直在尝试使用我在http://ipv6friday.org/blog/2012/06/ipv6-enabling-training/上的 reddit（所有地方）上找到的指南在我的网络上配置 IPv6 。现在乍一看，这似乎是工作，但是，我正在测试的机器，虽然它正确地从范围中获取地址，但并没有像我期望的那样路由 IPv6 作为演示：
[服务器] “ping6 -c 3 www.facebook.com”的输出

和
[客户端] “ping6 -c 3 www.facebook.com”的输出

相关配置的副本如下。我已经部分匿名化了使用的范围：
[服务器] /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;
};
};
[客户端] “sudo ifconfig”的输出

inet addr:192.168.1.31 Bcast:192.168.1.255 Mask:255.255.255.0

[客户端] “ip -6 route show dev wlan0”的输出
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
现在根据我的想法，这是在默认情况下尝试通过环回路由 IPv6，而不是通过 2a01 使用其他路由。我的问题是，这里发生了什么以及如何更改默认路由？
提前致谢！
