实验具体实施步骤：
$1__VE_ITEM__ 1. 首先对R1、R2和R3路由配置相应IP地址
$1__VE_ITEM__ a) 配置R1路由IP地址
r1(config)#interface f0/0
r1(config-if)#ip address 192.168.1.1 255.255.255.0
r1(config-if)#no shutdown
r1(config-if)#interface f0/1
r1(config-if)#ip address 192.168.2.1 255.255.255.0
r1(config-if)#no shutdown
r1(config-if)#interface f1/0
r1(config-if)#ip address 192.168.3.1 255.255.255.0
r1(config-if)#no shutdown
r1#show ip int b

r2(config-if)#no shutdown
r2(config-if)#interface f0/0
r2(config-if)#ip address 192.168.4.1 255.255.255.0
r2(config-if)#no shutdown
r2(config-if)#end
r2#show ip int b
Interface IP-Address OK? Method Status Protocol

$1__VE_ITEM__ d) 配置 PC机 ip地址
Pc1 ip 地址 192.168.1.10 子网掩码 255.255.255.0 默认网关 192.168.1.1
Pc2 ip 地址 192.168.5.20 子网掩码 255.255.255.0 默认网关 192.168.5.1
$1__VE_ITEM__ 2. 启动 RIP协议
$1__VE_ITEM__Ø 给 R2开启 RIP协议和查看路由条目
