动态路由Rip

Tip：Rip动态路由实现多个路由间不同网段通信。

本次实验目的，通过给ar1,ar2,ar3配置rip动态路由，实现pc1 ping通 pc2。

AR1配置如下：
<Huawei>sy
Enter system view, return user view with Ctrl+Z.
[Huawei]sys ar1
[ar1]
[ar1]int g0/0/0
[ar1-GigabitEthernet0/0/0]ip add 12.1.1.1 24
[ar1-GigabitEthernet0/0/0]int g0/0/1
[ar1-GigabitEthernet0/0/1]ip add 192.168.1.1 24

<ar1>sy
Enter system view, return user view with Ctrl+Z.
[ar1]rip 1
[ar1-rip-1]version 2
[ar1-rip-1]network 12.0.0.0
[ar1-rip-1]network 192.168.1.0

AR2配置如下：
<Huawei>sy
Enter system view, return user view with Ctrl+Z.
[Huawei]sys ar2
[ar2]int g0/0/0
[ar2-GigabitEthernet0/0/0]ip add 12.1.1.2 24
[ar2-GigabitEthernet0/0/0]int g0/0/1
[ar2-GigabitEthernet0/0/1]ip add 23.1.1.1 24

<ar2>sy
Enter system view, return user view with Ctrl+Z.
[ar2]rip 1
[ar2-rip-1]version 2
[ar2-rip-1]network 12.0.0.0
[ar2-rip-1]network 23.0.0.0

AR3配置如下：
<Huawei>sy
Enter system view, return user view with Ctrl+Z.
[Huawei]sys ar3
[ar3]int g0/0/0
[ar3-GigabitEthernet0/0/0]ip add 23.1.1.2 24
[ar3-GigabitEthernet0/0/0]int g0/0/1
[ar3-GigabitEthernet0/0/1]ip add 192.168.2.1 24

<ar3>sy
Enter system view, return user view with Ctrl+Z.
[ar3]rip 1
[ar3-rip-1]version 2
[ar3-rip-1]network 23.0.0.0
[ar3-rip-1]network 192.168.2.0

测试pc1 正常ping通 pc2

Rip路由的优化措施

Tip：rip路由以下一跳为参考，路线不一定最优。

本次实验目的：配置rip路由参数，控制流量走指定路线（最优路线）

在上面实验基础上 AR1连接AR3

AR1新增配置如下：
<ar1>sy
Enter system view, return user view with Ctrl+Z.
[ar1]int g0/0/2
[ar1-GigabitEthernet0/0/2]ip add 13.1.1.1 24
[ar1]rip 1
[ar1-rip-1]version 2
[ar1-rip-1]network 13.0.0.0
[ar1-GigabitEthernet0/0/2]rip metricin 2 //metricin 2 表示进来的路由跳数为2（in本身为0)
[ar1-GigabitEthernet0/0/2]rip metricout 3 //out 3 表示 出去的跳数为3（out本身为1）

AR3新增配置如下：
[ar3]int g0/0/2
[ar3-GigabitEthernet0/0/2]ip add 13.1.1.2 24
[ar3-GigabitEthernet0/0/2]q
[ar3]rip 1
[ar3-rip-1]version 2
[ar3-rip-1]network 13.0.0.0

pc1测试ping pc2 路由已发生改变，通过ar2到达ar3再到达pc2。
