想知道 ipv6 静态路由默认路由不起作用，只能 ping 直连接口，但 sh run 命令给出了我创建的到其他网络的静态路由，但在 sh run 输出中，我看到了我创建的用于获取全局单播地址的自动配置静态路由，在下一行，我看到了我创建的用于到达远程网络的静态路由，有什么想法吗？我看不到任何成功 ping 到远程网络的情况
我提供了更多信息，一行中有 3 个路由器，即路由器 A、路由器 B、路由器 C，它们通过快速以太网连接。中间路由器 B 已手动配置其 ipv6 地址，其他两个路由通过 ipv6 地址自动配置命令接收全局单播地址
这是路由器 A 的“Sh run”输出

定义了静态路由，为什么不能 ping 通！

为什么路由器A和C不能ping通？
感谢您的回答，我禁用了直接连接接口的一个静态路由，它仍然只能 ping 其直接连接的邻居，当我尝试从路由器 C 到路由器 b 时，甚至无法 ping 路由器 B 到路由器 A 的远程出口接口，这里我提供了配置更改后路由器 C 的 sh run 输出

答案1
如果我正确理解了配置，您既没有告诉路由器 A，也没有告诉路由器 C，它们应该使用路由器 B 来访问相应的其他网络（via 2001:DB6:3C4D:1::1，via 2001:DB6:3C4D:2::1而不是via ::）。事实上，您配置了 A 和 C两个都网络2001:DB6:3C4D:1::/64及其2001:DB6:3C4D:2::/64各自的本地链接。
