1.配置ip

$r1$ interface GigabitEthernet 0/0/0

$r1-GigabitEthernet0/0/0$ ip address 14.1.1.1 24

$r1$ interface lo0

$r1-LoopBack0$ ip address 1.1.1.1 24

$r2$ interface GigabitEthernet 0/0/0

$r2-GigabitEthernet0/0/0$ ip address 24.1.1.1 24

$r2$ interface LoopBack 0

$r2-LoopBack0$ ip address 2.2.2.2 24

$r3$ interface GigabitEthernet 0/0/0

$r3-GigabitEthernet0/0/0$ ip address 34.1.1.1 24

$r3$ interface LoopBack 0

$r3-LoopBack0$ ip address 3.3.3.3 24

$r4$ interface GigabitEthernet 0/0/0

$r4-GigabitEthernet0/0/0$ ip address 14.1.1.2 24

$r4$ interface GigabitEthernet 0/0/1

$r4-GigabitEthernet0/0/1$ ip address 34.1.1.2 24

$r4$ interface GigabitEthernet 0/0/2

$r4-GigabitEthernet0/0/2$ ip address 24.1.1.2 24

2.配置路由

$r1$ ip route-static 0.0.0.0 0 14.1.1.2

$r2$ ip route-static 0.0.0.0 0 24.1.1.2

$r3$ ip route-static 0.0.0.0 0 34.1.1.2

3.配置tunnel口

$r1$ interface Tunnel 0/0/0

$r1-Tunnel0/0/0$ ip address 10.1.1.1 24

$r1-Tunnel0/0/0$ tunnel-protocol gre p2mp

$r1-Tunnel0/0/0$ source 14.1.1.1

$r1-Tunnel0/0/0$ nhrp entry multicast dynamic #设置r1为nhrp服务器

$r1-Tunnel0/0/0$ nhrp network-id 100

$r2$ interface Tunnel 0/0/0

$r2-Tunnel0/0/0$ ip address 10.1.1.2 24

$r2-Tunnel0/0/0$ tunnel-protocol gre p2mp

$r2-Tunnel0/0/0$ source GigabitEthernet 0/0/0

$r2-Tunnel0/0/0$ nhrp entry 10.1.1.1 14.1.1.1 register

$r2-Tunnel0/0/0$ nhrp network-id 100

$r3$ interface Tunnel 0/0/0

$r3-Tunnel0/0/0$ ip address 10.1.1.3 24

$r3-Tunnel0/0/0$ tunnel-protocol gre p2mp

$r3-Tunnel0/0/0$ source GigabitEthernet 0/0/0

$r3-Tunnel0/0/0$ nhrp entry 10.1.1.1 14.1.1.1 register

$r3-Tunnel0/0/0$ nhrp network-id 100

#ping 10.1.1.1/10.1.1.2/10.1.1.3均能通

# $r1$ display nhrp peer all 查看map

4.配置路由联通环回地址

$r1$ rip 1

$r1-rip-1$ version 2

$r1-rip-1$ network 1.0.0.0 #宣告环回地址

$r1-rip-1$ network 10.0.0.0 #宣告逻辑接口

$r2$ rip 1

$r2-rip-1$ version 2

$r2-rip-1$ network 2.0.0.0

$r2-rip-1$ network 10.0.0.0

$r3$ rip 1

$r3-rip-1$ version 2

$r3-rip-1$ network 3.0.0.0

$r3-rip-1$ network 10.0.0.0

# $r2$ display ip routing-table 查看rip学到的路由

#r2学不到r3，r3学不到r2 ,RIP工作方式：往外发组播地址（224.0.0.9），在没有组播部署的情况下，发组播相当于发广播，发广播洪范给其他两个路由器。

#发送的伪广播：R1 源ip10.1.1.1 目标ip255.255.255.255，在前面裹一个报头源ip14.1.1.1，目标ip24/34 两个包

#真广播：发送一个包复制给其他人。伪广播：做几个包，单独发送给他们，全部能收到相当于广播的效果

#RIP特点：水平分割，从此口进不从此口出，需要关闭这个功能，就能实现r2把路由给r1,r1就能在同一个接口给r3

5.关闭中心路由器R1的水平分割

$r1$ interface Tunnel 0/0/0

$r1-Tunnel0/0/0$ undo rip split-horizon

$r3$ ping -a 3.3.3.3 2.2.2.2
