一、题目要求

1.R1与R5MPLS VPN

2.R6与R7MPLS VPN

3.R7可以访问R2/3/4的环回

二、拓扑

三、IP配置与环回

[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ip address 23.1.1.1 24
[r2-GigabitEthernet0/0/1]int lo0
[r2-LoopBack0]ip address 2.2.2.2 24
 
[r3]int g0/0/1
[r3-GigabitEthernet0/0/1]ip address 34.1.1.1 24
[r3-GigabitEthernet0/0/1]int g0/0/0

[r2]bgp 1
[r2-bgp]router-id 2.2.2.2
[r2-bgp]peer 4.4.4.4 as-number 1
[r2-bgp]peer 4.4.4.4 connect-interface LoopBack 0
[r2-bgp]ipv4-family vpnv4	
[r2-bgp-af-vpnv4]peer  4.4.4.4 enable                    --R2和R4建立VPN邻居关系
 
[r4]ip vpn-instance b2	                                 --B2
[r4-vpn-instance-b2]ipv4-family 
[r4-vpn-instance-b2-af-ipv4]route-distinguisher 1:1
[r4-vpn-instance-b2-af-ipv4]vpn-target 1:1
