实验11配置RIP

实验任务一：配置ripv1
1.建立物理连接

2.PC和路由器上配置ip地址
[RTA-GigabitEthernet0/0]ip address 192.168.0.1 24
[RTA-Serial1/0]ip address 192.168.1.1 24
[RTB-GigabitEthernet0/0]ip address 192.168.2.1 24
[RTB-Serial1/0]ip address 192.168.1.2 24
3.配置rip协议
[RTA]rip
[RTA -rip-1]network 192.168.1.0
[RTA -rip-1]network 192.168.0.0

[RTB]rip
[RTB -rip-1]network 192.168.1.0

实验任务二：配置ripv2

1. 建立物理连接
   

2. PC和路由器上配置ip地址
   [RTA]interface GigabitEthernet 0/0
   [RTA-GigabitEthernet0/0]ip address 192.168.0.1 24
   [RTA]interface GigabitEthernet 0/1
   [RTA-GigabitEthernet0/1]ip address 192.168.1.1 24

[RTB]interface GigabitEthernet 0/0
[RTB-GigabitEthernet0/0]ip address 10.0.0.1 24
[RTB]interface GigabitEthernet 0/1
[RTB-GigabitEthernet0/1]ip address 192.168.1.2 24

3. 配置RIPV1，观察路由表
   [RTA]rip 1
   [RTA-rip-1]network 192.168.0.0
   [RTA-rip-1]network 192.168.1.0

[RTB]rip 1
[RTB-rip-1]network 192.168.1.0
[RTB-rip-1]network 10.0.0.0

[RTA-rip-1]display ip routing-table

查看ip路由表发现，ripv1自动聚合。学习到路由10.0.0.0/8自然掩码。

4. 配置ripv2
   [RTA-rip-1]version 2
   [RTA-rip-1]undo summary

[RTB-rip-1]version 2
[RTB-rip-1]undo summary

[RTA-rip-1]display ip routing-table

由上面知道 ，ripv2取消自动聚合，可以学习到正确的路由10.0.0.0/24
但是还是存在路由10.0.0.0/8，原因是，rip路由的老化路由需要180s，到未收到路由更新180s。Rip才把其路由从ip路由表撤销。
