一、实验及拓扑
二、实验步骤
1、配置IP
R1
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.254 24
[R1-GigabitEthernet0/0/0]int s4/0/0
[R1-Serial4/0/0]ip add 15.1.1.1 24
[R1-Serial4/0/0]quit
R2
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip add 192.168.2.254 24
[R2-GigabitEthernet0/0/0]int s4/0/0
[R2-Serial4/0/0]ip add 25.1.1.2 24
[R2-Serial4/0/0]quit
R3
[R3]int g0/0/0
[R3-GigabitEthernet0/0/0]ip add 192.168.3.254 24
[R3-GigabitEthernet0/0/0]int s4/0/0
[R3-Serial4/0/0]ip add 35.1.1.3 24
[R3-Serial4/0/0]quit
R4
[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]ip add 45.1.1.4 24
[R4-GigabitEthernet0/0/0]int g0/0/1
[R4-GigabitEthernet0/0/1]ip add 192.168.4.254 24
[R4-GigabitEthernet0/0/1]quit
R5
[R5]int s4/0/1
[R5-Serial4/0/1]ip add 15.1.1.5 24
[R5-Serial4/0/1]int s3/0/1
[R5-Serial3/0/1]ip add 25.1.1.5 24
[R5-Serial3/0/1]int s4/0/0
[R5-Serial4/0/0]ip add 35.1.1.5 24
[R5-Serial4/0/0]int g0/0/0
[R5-GigabitEthernet0/0/0]ip add 45.1.1.5 24[R5]int l0
[R5-LoopBack0]ip add 5.5.5.5 24
[R5-LoopBack0]quit
2、认证
①PAP认证
R5（主认证方）
[R5]aaa
[R5-aaa]local-user wangdaye password cipher wdy12345
[R5-aaa]local-user wangdaye service-type ppp
[R5-aaa]quit[R5]int s4/0/1
[R5-Serial4/0/1]ppp authentication-mode pap
[R5-Serial4/0/1]quit
R1（被认证方）
[R1]int s4/0/0
[R1-Serial4/0/0]ppp pap local-user wangdaye password cipher way12345
用shutdown和undo shutdown做测试后，ping一下
②CHAP认证
R5（主认证方）【用刚刚创建的用户】
[R5]int s3/0/1
[R5-Serial3/0/1]ppp authentication-mode chap
[R5-Serial3/0/1]quit
R2（被认证方）
[R2]int s4/0/0
[R2-Serial4/0/0]ppp chap user wangdaye
[R2-Serial4/0/0]ppp chap password cipher wdy12345
[R2-Serial4/0/0]quit
同上，用shutdown和undo shutdown做测试后，ping一下
③HDLC封装
R3
查看协议
[R3]int s4/0/0
[R3-Serial4/0/0]dis th
[V200R003C00]
#
interface Serial4/0/0link-protocol pppip address 35.1.1.3 255.255.255.0
#
return
修改协议
[R3-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y
检查
R5
[R5]int s4/0/0
[R5-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y
检查
3、构建环境
①公网通（静态缺省）
R1
[R1]ip route-static 0.0.0.0 0 15.1.1.5R2
[R2]ip route-static 0.0.0.0 0 25.1.1.5R3
[R3]ip route-static 0.0.0.0 0 35.1.1.5R4
[R4]ip route-static 0.0.0.0 0 45.1.1.5
②检测
测R1的公网
测R2的公网
测R3的公网
③构建隧道
MGRE
R1
[R1]int Tunnel 0/0/0
[R1-Tunnel0/0/0]ip add 10.1.1.1 24
[R1-Tunnel0/0/0]tunnel-protocol gre p2mp
[R1-Tunnel0/0/0]source 15.1.1.1
Jul 26 2024 03:01:38-08:00 R1 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
on the interface Tunnel0/0/0 has entered the UP state.
[R1-Tunnel0/0/0]NHRP network-id 100
R2
[R2]int Tunnel 0/0/0
[R2-Tunnel0/0/0]ip add 10.1.1.2 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 10.1.1.1 15.1.1.1 registerR3
[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]ip add 10.1.1.3 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 10.1.1.1 15.1.1.1 register
GRE
R1
[R1]int Tunnel 0/0/1
[R1-Tunnel0/0/1]ip add 10.1.2.1 24
[R1-Tunnel0/0/1]tunnel-protocol gre
[R1-Tunnel0/0/1]source 15.1.1.1
[R1-Tunnel0/0/1]destination 45.1.1.4
R4
[R4]int Tunnel 0/0/1
[R4-Tunnel0/0/1]ip add 10.1.2.4 24
[R4-Tunnel0/0/1]tunnel-protocol gre
[R4-Tunnel0/0/1]source 45.1.1.4
[R4-Tunnel0/0/1]destination 15.1.1.1
4、配置RIP协议
R1
[R1]rip 1
[R1-rip-1]v 2
[R1-rip-1]undo su
[R1-rip-1]net 192.168.1.0
[R1-rip-1]net 10.0.0.0
R2
[R2]rip 1
[R2-rip-1]v 2
[R2-rip-1]undo su
[R2-rip-1]ne 192.168.2.0
[R2-rip-1]ne 10.0.0.0
R3
[R3]rip 1
[R3-rip-1]v 2
[R3-rip-1]undo summary
[R3-rip-1]ne 192.168.3.0
[R3-rip-1]ne 10.0.0.0
R4
[R4]rip 1
[R4-rip-1]v 2
[R4-rip-1]undo su
[R4-rip-1]ne 192.168.4.0
[R4-rip-1]ne 10.0.0.0
[R4-rip-1]quit
因为MGRE学不全，所以进行如下操作：（伪广播）
R1
[R1]int Tunnel 0/0/0
[R1-Tunnel0/0/0]nhrp entry multicast dynamic
[R1-Tunnel0/0/0]undo rip split-horizon
R2
[R2]int t0/0/0
[R2-Tunnel0/0/0]undo rip split-horizon
R3
[R3]int t0/0/0
[R3-Tunnel0/0/0]undo rip split-horizon
R1
R2
R3
R4 
5、做net
