MGER实验

1.ip分配及配置

 

 然后进行封装

 r2与r3认证 

[r2]aaa
[r2-aaa]local-user 1 password cipher 123456
[r2-aaa]local-user a service-type ppp
[r2-aaa]int s4/0/1   
[r2-Serial4/0/1]ppp authentication-mode pap

[r3-Serial4/0/0]ppp pap local-user 1 password cipher 123456

r2与r4认证

[r2]aaa  
[r2-aaa]local-user 2 password cipher 123456
[r2-aaa]local-user 2 service-type ppp
[r2]int s3/0/0
[r2-Serial3/0/0]ppp authentication-mode chap 

[r4-Serial4/0/0]ppp chap password cipher 123456

 

R1、R3、R4构建GMRE

先在r1、r3、r4上写上缺省路由

配置中心站点及支站点

[r1]int t0/0/0
[r1-Tunnel0/0/0]ip add 192.168.2.1 24       
[r1-Tunnel0/0/0]tunnel-protocol gre p2mp    
[r1-Tunnel0/0/0]source 1.1.1.2   
[r1-Tunnel0/0/0]nhrp entry multicast dynamic  
[r1-Tunnel0/0/0]nhrp network-id 5

[r3]int t0/0/0
[r3-Tunnel0/0/0]ip add 192.168.4.3 24  
[r3-Tunnel0/0/0]tunnel-protocol gre p2mp     
[r3-Tunnel0/0/0]source s4/0/0
[r3-Tunnel0/0/0]nhrp entry 192.168.4.1 1.1.1.2 register 
[r3-Tunnel0/0/0]nhrp network-id 5

[r4]int t0/0/0
[r4-Tunnel0/0/0]ip add 192.168.4.4 24  
[r4-Tunnel0/0/0]tunnel-protocol gre p2mp     
[r4-Tunnel0/0/0]source s4/0/0
[r4-Tunnel0/0/0]nhrp entry 192.168.4.1 1.1.1.2 register 
[r4-Tunnel0/0/0]nhrp network-id 5

r1、r3、r4生成的表

 

  6、rip获取路由，pc互通可以访问R2的环回
       6.1添加rip协议
[R1]rip 1
[R1-rip-1]vers 2
[R1-rip-1]network 192.168.4.0
[R1-rip-1]network 192.168.1.0
[r1-rip-1]int tu0/0/0 //rip是在虚拟接口实现的
[r1-Tunnel0/0/0]undo rip split-horizon
[r3]rip
[r3-rip-1]vers 2    
[r3-rip-1]network 192.168.4.0
[r3-rip-1]network 192.168.2.0
[r4]rip
[r4-rip-1]vers 2
[r4-rip-1]network 192.168.4.0
[r4-rip-1]network 192.168.3.0
