实验拓扑:
mpls-vpn步骤:
1.RIP2.MPLS
3.VRF
4.ip vrf forwarding
5.PE-CE间的路由协议
6.MP-BGP
7.不同VRF间通信,所需配置
8.测试成功
使用到的show 命令
show ip route
show ip int br
show ip bgp vpnv4 vrf A
show ip bgp vpnv4 all
show ip route vrf A
show ip vrf A
show mpls ldp neighbor
show mpls forwarding-table
show mpls ldp neighbor
show ip bgp all summary
R1#ping vrf A 8.8.8.8
R5#ping 8.8.8.8
9.有可能有的步骤和命令,没有写出来,大体思路是这样!
