一个人可以在一个接口上配置多个静态EIGRP邻居吗?除了禁用一个人应该考虑的水平分割之外,还有其他注意事项吗?

评论

使用静态邻居而不是多播发现有哪些注意事项?

在某些网络中,例如帧中继之类的非广播多路访问网络(NBMA),您将无法发现邻居,因此您可以在路由器eigrp配置模式下使用邻居命令

除了此注释之外,还可能有一些有关安全性和特定环路预防方案的具体原因。
有什么答案对您有帮助吗?如果是这样,您应该接受答案,这样问题就不会永远弹出来寻找答案。或者,您可以发布并接受自己的答案。

是的,那很好。

您可能还需要考虑在指向这些静态邻居的接口上添加“ no ip next-hop-self eigrp X”。这将启用“第三方下一个跃点”,这将允许分支路由器将流量直接发送到彼此,而不是通过集线器。
假设R1 <-> R2和R1 <-> R3(loop0-3.3。 3.3)
