RIPv2基本配置
1.实验目的
通过实验掌握：
（1）在路由器上启动RIPv2路由进程
（3）auto-summary的开启和关闭
（4）查看和调试RIPv2路由协议相关信息
2.拓扑结构

R2：
R2(config)#int lo0
R2(config-if)#ip add 3.3.3.3 255.255.255.0
R2(config-if)#no sh
R2(config-if)#int s0/1
R2(config-if)#ip add 13.1.1.2 255.255.255.0
R2(config-if)#no sh
R2(config-if)#exit
R2(config)#router rip
R2(config-router)#v 2
R2(config-router)#no auto-summary
R2(config-router)#network 13.0.0.0
R2(config-router)#network 3.0.0.0
4.实验调试
(1) show ip route
R0#sh ip ro
Codes: C - connected, S - static, 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
i - IS-IS, su - IS-IS summary, 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 - per
iodic downloaded static route
Gateway of last resort is not set
1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, Loopback0
2.0.0.0/24 is subnetted, 1 subnets
R 2.2.2.0 [120/1] via 12.1.1.2, 00:00:09, Serial0/0
3.0.0.0/24 is subnetted, 1 subnets
R 3.3.3.0 [120/2] via 12.1.1.2, 00:00:09, Serial0/0
12.0.0.0/24 is subnetted, 1 subnets
C 12.1.1.0 is directly connected, Serial0/0
13.0.0.0/24 is subnetted, 1 subnets
R 13.1.1.0 [120/1] via 12.1.1.2, 00:00:09, Serial0/0
（2）show ip protocols
R0#sh ip pro
Routing Protocol is "rip"

// RIPv2默认情况下只接收和发送版本2的路由更新
注意：
可以通过命令“ip rip send version”和“ip rip receive version”来控制在路由器接口上接收和发送的版本。
例如在s0/0接口上接收版本1和2的路由更新，但是只发送版本2的路由更新，配置如下：
R0(config-if)#ip rip send version 2
R0(config-if)#ip rip receive version 1 2
接口特性是优于进程特性的，虽然在RIP进程中配置了“version 2” ， 但是如果在接口上配置了“ip rip receive version 1 2” ，则该接口可以接收版本1和 2的路由更新。
