router rip //启用路由协议RIP
version 2 //使用的是RIPv2，如果没有这句，则是使用RIPv1
network 172.16.0.0 //宣告直连的网段
exit
三层交换机配置：
ip route 0.0.0.0 0.0.0.0 172.16.9.250 //缺省路由，所有在路由表中没有办法匹配的数据包，都发向下一跳地址为172.16.9.250这个路由器
line con 0
line aux 0
line vty 0 15 //telnet线路(路由器只有5个，是0-4)
password 12345678 //login密码
login
end
copy running-config startup-config 保存配置。
