实验要求
- R1与R5 MPLS VPN
- R6与R7 MPLS VPN
- R7可以访问R2/3/4的环回
实验拓扑
实验配置
1.IP接口地址及路由器环回地址配置
[Huawei]sysname r2
[r2]int LoopBack 0
[r2-LoopBack0]ip add 2.2.2.2 24
[r2-LoopBack0]int g0/0/1
[r2-GigabitEthernet0/0/1]ip add 23.1.1.1 24
[Huawei]sysname r3
[r3]int LoopBack 0
[r3-LoopBack0]ip add 3.3.3.3 24
[r3-LoopBack0]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 23.1.1.2 24
[r3-GigabitEthernet0/0/0]int g0/0/1
[r3-GigabitEthernet0/0/1]ip add 34.1.1.1 24
[Huawei]sysname r4
[r4]int LoopBack 0
[r4-LoopBack0]ip add 4.4.4.4 24
[r4-LoopBack0]int g0/0/0
[r4-GigabitEthernet0/0/0]ip add 34.1.1.2 24
[r4-GigabitEthernet0/0/0]int g0/0/2
[r4-GigabitEthernet0/0/2]ip add 47.1.1.1 24
[Huawei]sysname r7
[r7]int g0/0/2
[r7-GigabitEthernet0/0/2]ip add 47.1.1.2 24
2.在R2、R3、R4内启动OSPF，构建公网，构建MPLS
配置OSPF
[r2]ospf 1 router-id 2.2.2.2
[r2-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]network 23.1.1.1 0.0.0.0

[r4]ospf 1
[r4-ospf-1]silent-interface g0/0/2
配置静默接口，静止收发Hello报文，但不妨碍R4通过OSPF学习去往这两个接口所在网段的路由
[r7]ip route-static 0.0.0.0 0 47.1.1.1
在R7上配置静态路由
配置MPLS
