一、实验拓扑: 二、命令部署: R1(config)#int f0/0 R1(config-if)#no shutdown R1(config-if)#ip add 12.1.1.1 255.255.255.0

R1(config)#int lo1 R1(config-if)#ip add 172.16.1.1 255.255.255.0 R1(config-if)#int lo2 R1(config-if)#ip add 172.16.2.1 255.255.255.0 R1(config-if)#int lo3 R1(config-if)#ip add 172.16.3.1 255.255.255.0

R1(config)#router rip R1(config-router)#version 2 R1(config-router)#no auto-summary R1(config-router)#network 12.1.1.1 R1(config-router)#network 172.16.1.1 R1(config-router)#network 172.16.2.1 R1(config-router)#network 172.16.3.1

R2(config)#int f0/0 R2(config-if)#no shutdown R2(config-if)#ip add 12.1.1.2 255.255.255.0 R2(config)#int f0/1 R2(config-if)#no shutdown R2(config-if)#ip add 23.1.1.2 255.255.255.0

R2(config)#router rip R2(config-router)#version 2 R2(config-router)#no auto-summary R2(config-router)#network 12.1.1.2 R2(config-router)#network 23.1.1.2

R3(config)#int f0/0 R3(config-if)#no shutdown R3(config-if)#ip add 23.1.1.3 255.255.255.0

R3(config)#router rip R3(config-router)#version 2 R3(config-router)#no auto-summary R3(config-router)#network 23.1.1.3 注意:router rip 中不能有no auto-summary命令 三、验证: 1、未部署汇总前,都是单独的: R3#show ip route 23.0.0.0/24 is subnetted, 1 subnets C 23.1.1.0 is directly connected, FastEthernet0/0 172.16.0.0/24 is subnetted, 3 subnets R 172.16.1.0 [120/2] via 23.1.1.2, 00:00:24, FastEthernet0/0 R 172.16.2.0 [120/2] via 23.1.1.2, 00:00:24, FastEthernet0/0 R 172.16.3.0 [120/2] via 23.1.1.2, 00:00:24, FastEthernet0/0 12.0.0.0/24 is subnetted, 1 subnets R 12.1.1.0 [120/1] via 23.1.1.2, 00:00:24, FastEthernet0/0

2、部署汇总命令后: R1(config)#int f0/0 R1(config-if)#ip summary-address rip 172.16.0.0 255.255.0.0 R3#clear ip route * R3#show ip rip database

①以下为自动汇总结果: R3#show ip route 23.0.0.0/24 is subnetted, 1 subnets C 23.1.1.0 is directly connected, FastEthernet0/0 R 172.16.0.0/16 [120/2] via 23.1.1.2, 00:00:20, FastEthernet0/0 12.0.0.0/24 is subnetted, 1 subnets R 12.1.1.0 [120/1] via 23.1.1.2, 00:00:20, FastEthernet0/0

R3#show ip rip database 12.0.0.0/8 auto-summary 12.0.0.0/8 [1] via 23.1.1.2, 00:00:09, FastEthernet0/0 12.1.1.0/24 [1] via 23.1.1.2, 00:01:59, FastEthernet0/0 23.0.0.0/8 auto-summary 23.1.1.0/24 directly connected, FastEthernet0/0 172.16.0.0/16 auto-summary 172.16.0.0/16 [1] via 23.1.1.2, 00:00:09, FastEthernet0/0 ②以下为手工汇总结果:
