MPLS实验

实验要求

1、R1与R5MPLS VPN
2、R6与R7MPLS VPN
3、R7可以访问R2/3/4的环回

mpls  vpn  在R2/4上面分别做两个VPN

[r2]ip vpn-instance a   

[r2-vpn-instance-a]ipv4-family    

[r2-vpn-instance-a-af-ipv4]route-distinguisher 1:1   

[r2-vpn-instance-a-af-ipv4]vpn-target 1:1   

[r2]interface GigabitEthernet 0/0/1   

[r2-GigabitEthernet0/0/1]ip binding vpn-instance a  

[r2-GigabitEthernet0/0/1]ip address 192.168.2.2 24 

 

[r4]ip vpn-instance b  

[r4-vpn-instance-a]ipv4-family    

[r4-vpn-instance-a-af-ipv4]route-distinguisher 1:1   

[r4-vpn-instance-a-af-ipv4]vpn-target 1:1   

[r4]interface GigabitEthernet 0/0/0
