4.配置MPLS-VPN

连接R1接口
[r2]ip -instance a                              创建名为a的空间
[r2--instance-a]ipv4-family                     进入IPV4的配置模式下
[r2--instance-a-af-ipv4]route-distinguisher 1:1   RD值
[r2--instance-a-af-ipv4]-target 1:1          RT值 必须对端的PE端一致
[r2]int g 0/0/0                进入链接CE端的接口
[r2-GigabitEthernet0/0/0]ip binding -instance a  关联到空间
[r2-GigabitEthernet0/0/0]ip address 192.168.2.2 24   配置私有ip地址

连接R6接口：
[r2]ip -instance b    
[r2--instance-b]ipv4-family
[r2--instance-b-af-ipv4]route-distinguisher 2:2
[r2--instance-b-af-ipv4]-target 2:2
[r2--instance-b-af-ipv4]q
[r2--instance-b]q
[r2]int g 0/0/1
[r2-GigabitEthernet0/0/2]ip binding -instance b
[r2-GigabitEthernet0/0/2]ip address 192.168.2.2 24

连接R5接口
[r4]ip -instance a1    
[r4--instance-a]ipv4-family
[r4--instance-a-af-ipv4]route-distinguisher 1:1    
[r4--instance-a-af-ipv4]-target 1:1
[r4--instance-a-af-ipv4]q
[r4--instance-a]q
[r4]int g 0/0/1    
[r4-GigabitEthernet0/0/1]ip binding -instance a1
[r4-GigabitEthernet0/0/1]ip add 192.168.3.1 24

连接R7接口
[r4]ip -instance b1
[r4--instance-b]ipv4-family 
[r4--instance-b-af-ipv4]route-distinguisher 2:2
[r4--instance-b-af-ipv4]-target 2:2
[r4--instance-b-af-ipv4]q
[r4--instance-b]q
[r4]interface g0/0/1
[r4-GigabitEthernet0/0/2]ip binding -instance b1
[r4-GigabitEthernet0/0/2]ip address 192.168.3.1 24
 

5.配置MP-BGP

[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 lo 0
[r2-bgp]ipv4-family v4
[r2-bgp-af-v4]peer 4.4.4.4 enable 

[r4]bgp 1
[r4-bgp]route-select
[r4-bgp]router-id 4.4.4.4
[r4-bgp]peer 2.2.2.2 as-number 1
[r4-bgp]peer 2.2.2.2 connect-interface lo 0
[r4-bgp]ipv4-family v4
[r4-bgp-af-v4]peer 2.2.2.2 enable 
 

6.配置客户环回和ip地址

[r1]int lo 0
[r1-LoopBack0]ip add 192.168.1.1 24
[r1-LoopBack0]int g 0/0/0
[r1-GigabitEthernet0/0/1]ip ad 192.168.2.1 24

[r6]int lo 0
[r6-LoopBack0]ip add 192.168.1.1 24
[r6-LoopBack0]int g0/0/0
[r6-GigabitEthernet0/0/1]ip add 192.168.2.1 24

[r5]int g0/0/0
[r5-GigabitEthernet0/0/0]ip add 192.168.3.2 24
[r5-GigabitEthernet0/0/0]int lo 0
[r5-LoopBack0]ip add 192.168.4.1 24

[r7]int lo 0
[r7-LoopBack0]ip add 192.168.4.2 24
[r7-LoopBack0]int g0/0/0
[r7-GigabitEthernet0/0/0]ip add 192.168.3.2 24
 

7.配置动态

[r6]rip 1
[r6-rip-1]version 2
[r6-rip-1]un summary 
[r6-rip-1]network 192.168.1.0 
[r6-rip-1]network 192.168.2.0

[r2]rip 1 -instance b
[r2-rip-1]network 192.168.2.0

R2上的vrf的b空间路由表可以看到已经通过rip学习到 192.168.1.0路由

[r7]ospf 1 router-id 7.7.7.7
[r7-ospf-1]area 0 
[r7-ospf-1-area-0.0.0.0]network 192.168.3.2 0.0.0.0
[r7-ospf-1-area-0.0.0.0]network 192.168.4.2 0.0.0.0

[r4]ospf 2 -instance b1  在vrp空间b1上启动ospf进程2
[r4-ospf-2]area 0
[r4-ospf-2-area-0.0.0.0]network 192.168.3.1 0.0.0.0
 

8.双向重发布

[r2]rip 1 -instance b   
[r2-rip-1]import-route bgp    ----把BGP重发布进rip
 
[r2]bgp 1
[r2-bgp]ipv4-family -instance b
[r2-bgp-b]import-route rip 1   ---把rip重发布进BGP
  
[r4]bgp 1
[r4-bgp]ipv4-family -instance b1
[r4-bgp-b1]import-route ospf 2 ---把ospf 2重发布进BGP 
 
[r4]ospf 2 -instance b1
[r4-ospf-2]import-route bgp ----把BGP重发布进ospf 2
