求助，我懵逼了两台交换机夹在中间都不知道如何配置，有大佬能给个思路方向如何配置？贡献实验图片 没有VLAN相关的东西,交换机放在那就好,不用配置的 学习 本帖最后由 leort 于 2021-5-9 17:35 编辑
稍微敲了一遍 应该都符合需求
真的做不了可以参考一下,就是接口类型有点差别

你要參考一下關於 OSPF virtual-link的交章。
樓上大概應該是對的。

嗯嗯，谢谢指引 本帖最后由 itwong 于 2021-6-20 12:33 编辑
这个是OSPF network type broadcast,也就是需要DR/BDR.
R4上f1/0, R6上f1/0跟R1上的f1/0都是同一个L2 domain(172.8.146.0/24)
同理， R4上f1/1, R6上f1/1跟R5上的f1/0都是同一个L2 domain(172.8.100.0/24)
而area 35跟23是serial， 所以是OSPF network point-to-point. 没有DR/BDR选举，但area 23并没有直接连到area 0，需要virtual-link
