[网络协议]MGRE综合实验

?IP地址配置，并配置缺省

[R1]int  s 4/0/0
[R1-Serial4/0/0]ip add 15.0.0.1 24
[R1]int g 0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[R1]ip route-static 0.0.0.0 0 15.0.0.2

[R2]int s 4/0/0
[R2-Serial4/0/0]ip add 25.0.0.1 24
[R2]int g 0/0/0
[R2-GigabitEthernet0/0/0]ip add 192.168.2.1 24
[R2]ip route-static 0.0.0.0 0 25.0.0.2

[R3]int s 4/0/0
[R3-Serial4/0/0]ip add 35.0.0.1 24
[R3]int g 0/0/0
[R3-GigabitEthernet0/0/0]ip add 192.168.3.1 24
[R3]ip route-static 0.0.0.0 0 35.0.0.2

[R4]int g 0/0/0
[R4-GigabitEthernet0/0/0]ip add 45.0.0.1 24
[R4]int g 0/0/1
[R4-GigabitEthernet0/0/1]ip add 192.168.4.1 24
[R4]ip route-static 0.0.0.0 0 45.0.0.2

[ISP]int s 3/0/0
[ISP-Serial3/0/0]ip add 15.0.0.2 24
[ISP]int s 3/0/1
[ISP-Serial3/0/1]ip add 25.0.0.2 24
[ISP]int s 4/0/0
[ISP-Serial4/0/0]ip add 35.0.0.2 24
[ISP]int g 0/0/0
[ISP-GigabitEthernet0/0/0]ip add 45.0.0.2 24
[ISP]int lo1
[ISP-LoopBack1]ip add 5.5.5.5 24

R1和R5之间使用PPP的PAP认证，R5为主认证方

因为华为串线链路默认为PPP，所以直接进行认证配置即可

在认证方配置认证并开启认证

[ISP]aaa
[ISP-aaa]local-user admin password cipher 111222
[ISP-aaa]local-user admin service-type ppp
[ISP]int s 3/0/0
[ISP-Serial3/0/0]ppp authentication-mode pap 

被认证方与认证方连接

[R1]int s 4/0/0
[R1-Serial4/0/0]ppp pap local-user admin password cipher 111222

可以ping通，即认证成功

?R2和R5之间使用PPP的chap认证，R5为主认证方

在认证方开启认证

[ISP]int s 3/0/1
[ISP-Serial3/0/1]ppp authentication-mode chap 

被认证方与认证方连接

[R2]int s 4/0/0
[R2-Serial4/0/0]ppp chap user admin 
[R2-Serial4/0/0]ppp chap password cipher 111222

可以ping通，即认证成功

??R3和R5之间使用HDLC封装

两边接口都需要改成hdlc封装

[R3]int s 4/0/0
[R3-Serial4/0/0]link-protocol hdlc 

[ISP]int s 4/0/0
[ISP-Serial4/0/0]link-protocol hdlc 

R1/R2/R3构建一个MGRE环境，R1为中心站点

[R1]int t 0/0/0
[R1-Tunnel0/0/0]ip add 192.168.5.1 24
[R1-Tunnel0/0/0]tunnel-protocol gre p2mp 
[R1-Tunnel0/0/0]sou	
[R1-Tunnel0/0/0]source 15.0.0.1
[R1-Tunnel0/0/0]nhrp network-id 100
[R1-Tunnel0/0/0]nhrp entry multicast dynamic 

[R2]int t 0/0/0
[R2-Tunnel0/0/0]ip add 192.168.5.2 24
[R2-Tunnel0/0/0]tunnel-protocol gre p2mp 
[R2-Tunnel0/0/0]source Serial 4/0/0
[R2-Tunnel0/0/0]nhrp network-id 100
[R2-Tunnel0/0/0]nhrp entry 192.168.5.1 15.0.0.1 register 

[R3]int  t 0/0/0
[R3-Tunnel0/0/0]ip add 192.168.5.3 24
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp 
[R3-Tunnel0/0/0]source Serial 4/0/0
[R3-Tunnel0/0/0]nhrp network-id 100
[R3-Tunnel0/0/0]nhrp entry 192.168.5.1 15.0.0.1 register 

R1,R4间为点到点的GRE

[R1]int t 0/0/1
[R1-Tunnel0/0/1]ip add 192.168.6.1 24
[R1-Tunnel0/0/1]tunnel-protocol gre 
[R1-Tunnel0/0/1]source 15.0.0.1
[R1-Tunnel0/0/1]description 45.0.0.1

[R4]int t 0/0/0
[R4-Tunnel0/0/0]ip add 192.168.6.2 24
[R4-Tunnel0/0/0]tunnel-protocol gre 
[R4-Tunnel0/0/0]source 45.0.0.1
[R4-Tunnel0/0/0]description 15.0.0.1

基于RIP全网可达

?

?所有PC设置IP为源IP

?私网访问公网
