cisco-ios - Brocade NetIron CER 2024C BGP 配置问题

问题描述

我是 Brocade/NetIron 的新手，但我认为配置类似于 Cisco，直到我们尝试连接一个新的传输提供商。路由似乎没有正确加载，我们在我们添加到接口的 Cogent 发布的 IP 上 ping 路由器时遇到问题。

谁能看到这个配置有问题？

我可以ping Cogent 的IP，xxx41 很好。

我无法从外界 ping 我的路由器。Cogent 也无法 ping 我 - xxx42。

解决方案

确保您有默认路由。

ip 路由 0.0.0.0/0 xxxx

其中 xxxx 是您的可靠网关。
