6to4 隧道配置

我在虚拟机上配置 6to4 时遇到问题。我有两台装有 ubuntu 的机器。

会议第一台机器：

#ip tunnel del tun6to4                     
#ip tunnel add tun6to4 mode sit ttl 64 remote any local 150.254.34.1
#ip link set dev tun6to4 up
#ip -6 addr add 2002:a02d:1701::1/16 dev tun6to4

会议第二台机器：

# ip tunnel del tun6to4                   
#ip tunnel add tun6to4 mode sit ttl 64 remote any local 160.45.23.1
#ip link set dev tun6to4 up
#ip -6 addr add 2002:96fe:2201:1/16 dev tun6to4

我尝试 ping 机器：在第一台机器上 ping 160.45.23.1，在第二台机器上 ping 150.254.34.1，结果无连接之间。

是什么原因？

这是我的地址：
