[R3]ip route-static 0.0.0.0 0 35.1.1.5

[R4]ip route-static 0.0.0.0 0 45.1.1.5

3.R1和R5之间使用PPP的PAP认证，R5为主认证方

（1）主认证方：

        [R5]aaa
        [R5-aaa]local-user hhp password cipher 12345
        Info: Add a new user.
        [R5-aaa]local-user hhp service-type ppp
        [R5-aaa]q
        [R5]
        [R5]int s4/0/1
        [R5-Serial4/0/1]ppp authentication-mode PAP
        [R5-Serial4/0/1]q
        [R5]

（2）被认证方：

        [R1]int s4/0/0
        [R1-Serial4/0/0]ppp pap local-user hhp password cipher 12345
        [R1-Serial4/0/0]q
        [R1]

4.R2和R5之间使用PPP的chap认证，R5为主认证方

（1）主认证方：

        [R5]aaa
        [R5-aaa]local-user hhp2 password cipher 123456
        Info: Add a new user.
        [R5-aaa]local-user hhp2 service-type ppp
        [R5-aaa]q
        [R5]int s3/0/1
        [R5-Serial3/0/1]ppp authentication-mode chap
        [R5-Serial3/0/1]q
        [R5]

[R2]int s 4/0/0
[R2-Serial4/0/0]ppp chap user hhp2
[R2-Serial4/0/0]ppp chap password cipher 123456

5.R3与R5之间使用HDLC封装

（1）R3上的配置：

        [R3]int s4/0/0
        [R3-Serial4/0/0]link-p
        [R3-Serial4/0/0]link-protocol hdlc
        Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
        :y

（2）R5上的配置：

        [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

6.R1,R2,R3,构成一个MGRE环境，R1为站点中心；

MGRE VPN:10.1.2.0/24

创建隧道Tunnel 0/0/0，并加入到同一个nhrp中，配置如下：

[R1]int Tunnel 0/0/0
[R1-Tunnel0/0/0]ip add 10.1.2.1 24
[R1-Tunnel0/0/0]tunnel-protocol gre p2mp
[R1-Tunnel0/0/0]source 15.1.1.1
Mar 30 2024 15:09:20-08:00 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]
[R1-Tunnel0/0/0]nhrp network-id 100

[R2]int Tunnel 0/0/0
[R2-Tunnel0/0/0]ip add 10.1.2.2 24
[R2-Tunnel0/0/0]tunnel-protocol gre p2mp
[R2-Tunnel0/0/0]source Serial 4/0/0
Mar 30 2024 15:12:37-08:00 R2 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
on the interface Tunnel0/0/0 has entered the UP state.
[R2-Tunnel0/0/0]nhrp network-id 100
[R2-Tunnel0/0/0]

[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]ip add 10.1.2.3 24
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp
[R3-Tunnel0/0/0]source Serial 4/0/0
Mar 30 2024 15:16:13-08:00 R3 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
on the interface Tunnel0/0/0 has entered the UP state.
[R3-Tunnel0/0/0]nhrp network-id 100
[R3-Tunnel0/0/0]

7.R1,R4之间为点到点GRE

GRE VPN:10.1.1.0/24

[R1]int Tunnel 0/0/1
[R1-Tunnel0/0/1]ip add 10.1.1.1 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
[R1-Tunnel0/0/1]

[R4]int Tunnel 0/0/1
[R4-Tunnel0/0/1]ip add 10.1.1.4 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
[R4-Tunnel0/0/1]q

8.整个私有网络通过rip路由协议全网互通

[R1]rip 1
[R1-rip-1]v 2
[R1-rip-1]undo summary
[R1-rip-1]network 192.168.1.0
[R1-rip-1]network 10.0.0.0
[R1-rip-1]

[R2]rip 1
[R2-rip-1]v 2
[R2-rip-1]undo summary
[R2-rip-1]network 192.168.2.0
[R2-rip-1]network 10.0.0.0
[R2-rip-1]

[R3]rip 1
[R3-rip-1]v 2
[R3-rip-1]undo summary
[R3-rip-1]network 192.168.3.0
[R3-rip-1]network 10.0.0.0
[R3-rip-1]

[R4]rip 1
[R4-rip-1]v 2
[R4-rip-1]undo summary
[R4-rip-1]network 192.168.4.0
[R4-rip-1]network 10.0.0.0
[R4-rip-1]

中心站点开启隧道的广播功能：
[R1]int Tunnel 0/0/0
[R1-Tunnel0/0/0]nhrp entry multicast dynamic
[R1-Tunnel0/0/0]q

其他的向中心站点开启注册：
[R2]int Tunnel 0/0/0
[R2-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register

[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register

关闭mgre水平分割机制

[R1-Tunnel0/0/0]undo rip split-horizon

[R2-Tunnel0/0/0]undo rip split-horizon

[R3-Tunnel0/0/0]undo rip split-horizon

9.所有PC设置私有IP为源IP，可以访问R5环回，达到全网通
