MPLS VPN 问题求助

kingair

拓扑图如下，要求PC1 能ping 通PC2，  两个路由器建立MPLS的 隧道，



我的配置如下， 现在是 死活ping不通 ，但是我感觉配置没有问题，请各位大侠指点！！！

不知掉 个人仁兄有什么看法？？？？

kingair

还没有仁兄。。。发现问题吗？？哎。。。求助ing

MPLS VPN上 R1和R2上没看到BGP的配置哦。局域网的数据要跨越公网，但是公网又不识别这些私有地址，怎么办？MPLS的作用就显示出来了：在IP数据包前加上一个LABEL 。跨越公网是不看IP，看LABEL，实现了路由的传递。重点就是，这个LABEL 就是要依靠BGP的团体属性 通告给邻居的

kingair

不是的， MPLS VPN 好多种类的，
你那个是 bgp MPLS VPN ， 我这个是 L2的 VPN，

kingair

把我的帖子顶起来。。。。

二层的没试过，坐等高手

wantccie

vrf在哪里？
CE和PE之间用什么路由协议？

kingair

    税说用MPLS 就要有VRF啊？？？？
