先設定R1、R2的網路環境，再進行互ping。
基本設定完成後，請對R1、R2輸入以下指令:
router rip
network 10.1.1.1
router rip
network 10.1.2.1
開啟R1的capture檢視

R3路由器經由前面的步驟透過do show ip route得到:
10.1.1.0/24 [120/1] via 10.1.2.1 ...
10.1.2.0/24 ...

router rip
network 10.1.2.2
透過上述可以完成R1-R3的連接且能互相傳送資料。
```

```
R2:
int e0/1
ip addr 192.168.1.1 255.255.255.0
R3:
int e0/0
ip addr 192.168.1.2 255.255.255.0
R1先檢查ip route，在做:
router rip
version 2
R2、R3:
router rip
version 2
R2:
network 192.168.1.1
```
