R1(config-if)#ip address 12.1.1.1 255.255.255.0
R1(config-if)#exit
R1(config)#router rip --進入并啟用RIP配置模式
R1(config-router)#version 2 --指定版本2
R1(config-router)#no auto-summary --不要自動彙總
R1(config-router)#network 12.1.1.0 --宣告直連的網段
R1(config-router)#network 192.168.1.0 --宣告直連的網段
R1(config-router)#end
檢視路由表:
R1#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
12.0.0.0/24 is subnetted, 1 subnets
C 12.1.1.0 is directly connected, FastEthernet0/1
C 192.168.1.0/24 is directly connected, FastEthernet0/0
R 192.168.2.0/24 [120/1] via 12.1.1.2, 00:00:04, FastEthernet0/1
R是通過RIP路由學習到 192.168.2.0/24網段
R2:
Router(config)#hostname R2
R2(config)#interface f0/1
R2(config-if)#ip address 12.1.1.2 255.255.255.0
R2(config-if)#no sh
R2(config)#interface f0/0
R2(config-if)#ip address 192.168.2.254 255.255.255.0
R2(config-if)#exit
R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 192.168.2.0
R2(config-router)#network 12.1.1.0
R2(config-router)#end
R2#show ip route
R 192.168.1.0/24 [120/1] via 12.1.1.1, 00:00:20, FastEthernet0/1
C 192.168.2.0/24 is directly connected, FastEthernet0/0

總結:
RIP的工作原理在前面都有介紹,下面解釋一下為什麼要指定版本2(version 2),版本1與版本2最大的差別就是,2是以多點傳播的方式發送更新,位址為224.0.0.9,且支援可變長子網路遮罩,而1是
廣播的方式發送更新,且不支援變長子網路遮罩!
