mpls vpn有路由ping不通.求高手解答

R4 和 R5是客户端路由器.
R4和 R2的fa0/0运行rip
R5和 R3的fa0/0运行eigrp
在R2和R3都做了单点双向重分发，客户段路由器R4 R5都有对方路由，但是都不通.为什么....  配置如下，求高手赐教

MPLS域内的设备上要敲上：
mpls label range 100 199
mpls label protocol ldp
mpls ldp router-id Loopback0
接口下敲上：
mpls ip
要建立起LDP邻居，其次再考虑有没有路由黑洞之类的，你试试吧。。。

R4 ping不通R5的任何接口.在R5上debug ip icmp 没有收到R4的ping包

知不智

你可以一段段抓包看一下，看现象，还有虽然说tag-switching ip和mpls ip 效果一样，你试下换成mpls ip

好的  我等下试试  如果能找到原因再告诉你们是什么问题

cwuyuwen

多谢朋友   最好百度一下  结果是 p路由器和pe路由器的lookback口要设置成32位...
现在可以ping同了
我好辛苦......开始ping不通 心都碎了{:soso_e118:}
