CCNA-RIPv2的认证和触发更新配置实验.docx

1、 实验目的：通过本次的使用，我们可以掌握如下技能1) RIPv2明文认证的配置和匹配原则。2) RIPv2 MD5认证的配置和匹配原则。3) RIPv2的触发更新。2、 实验拓扑图：3、 实验步骤：(1)根据网络拓扑图说明，配置各个接口的地址。R!(config)#hostname R1R1(config)#interface loopback 0R1(config-if)#ip adR1(config-if)#ip address 1.1.1.1 255.255.255.0R1(config-if)#no shR1(config-if)#no shutdownR1(config)#interface serial 0/1R1(config-if)#ip address 192.168.1.1 255.255.255.0R1(config-if)#no shR1(config-if)#no shutdownR1(config-if)#endR1#Router(config)#hostname R2R2(config)#interface sR2(config)#interface serial 0/1R2(config-if)#clR2(config-if)#clock rR2(config-if)#clock rate 128000R2(config-if)#ip adR2(config-if)#ip address 192.168.1.2 255.255.255.0R2(config-if)#no shR2(config-if)#no shutdownR2(config-if)#endR2(config)#interface serial 0/2R2(config-if)#ip adR2(config-if)#ip address 192.168.2.1 255.255.255.0R2(config-if)#no shR2(config-if)#no shutdownR2(config-if)#Router(config)#hosRouter(config)#hostname R3R3(config)#interface serial 0/2R3(config-if)#ip adR3(config-if)#ip address 192.168.2.2 255.255.255.0R3(config-if)#clock rate 128000R3(config-if)#no shR3(config-if)#no shutdownR3(config-if)#exitR3(config)#interface serial 0/3R3(config-if)#ip adR3(config-if)#ip address 192.168.3.1 255.255.255.0R3(config-if)#no shutdownR3(config-if)#R4(config)#intR4(config)#interface sR4(config)#interface serial 0/3R4(config-if)#ip adR4(config-if)#ip address 192.168.3.2 255.255.255.0R4(config-if)#no sR4(config-if)#no shR4(config-if)#no shutdownR4(config-if)#exit(2)启用RIPV2R1(config)#router ripR1(config-router)#verR1(config-router)#version 2R1(config-router)#network 1.0.0.0R1(config-router)#network 192.1681.0R1(config-router)#注：启用RIPv2，并将去网络发布出去R2(config)#router ripR2(config-router)#verR2(config-router)#version 2R2(config-router)#no auR2(config-router)#no auto-summaryR2(config-router)#netR2(config-router)#network 192.168.1.0R2(config-router)#network 192.168.2.0R2(config-router)#R3(config)#router ripR3(config-router)#veR3(config-router)#version 2R3(config-router)#netR3(config-router)#network 192.168.2.0R3(config-router)#network 192.168.3.0R3(config-router)#R4(config)#router ripR4(config-router)#veR4(config-router)#version 2R4(config-router)#no auR4(config-router)#no auto-summaryR4(config-router)#network 192.168.3.0(3)配置RIPv2的认证R1(config)#key chain xiaR1(config-keychain)#key 1R1(config-keychain-key)#key-string xiajiangR1(config-keychain-key)#exitR1(config)#interface serial 0/0R1(config-if)#ip rip authentication keR1(config-if)#ip rip authentication key-chain xiaR1(config-if)#ip rip triggeredR1(config-if)#注：启用RIPv2的认证R2(config)#key chain xiaR2(config-keychain)#key 1R2(config-keychain-key)#keR2(config-keychain-key)#key-string xiajiangR2(config-keychain-key)#endR2(config)#interface s0/0R2(config-if)#ip rR2(config-if)#ip riR2(config-if)#ip rip triR2(config-if)#ip rip triggeredR2(config-if)#ip rip authentication key-chain xiaR2(config-if)#exitR2(config)#interface serial 0/1R2(config-if)#ip rip authentication key-chain xiaR2(config-if)#ip rip triggeredR2(config-if)#R3(config)#key chain xiaR3(config-keychain)#key 1R3(config-keychain-key)#key-string xiajiangR3(config-keychain-key)#exitR3(config-keychain)#exitR3(config)#interface serial 0/1R3(config-if)#ip rip authentication key-chain xiaR3(config-if)#ip rip triggeredR3(config-if)#exitR3(config)#interface serial 0/2R3(config-if)#ip rip authentication key-chain xiaR3(config-if)#ip rip triggeredR3(config-if)#R4(config)#key chain xiaR4(config-keychain)#key 1R4(config)#interface serial 0/2R4(config-if)#ip rip authentication key-chain xiaR4(config-if)#ip rip triggeredR4(config-if)#(4)测试配置情况R1#show ip proR1#show ip protocolsRouting Protocol is ripSending updates every 30 seconds, next due in 1 secondsInvalid after 180 seconds, hold down 180, flushed after 240Outgoing update filter list for all interfaces is not setIncoming update filter list for all interfaces is not setRedistributing: ripDefault version control: send version 2, receive version 2Interface Send Recv Triggered RIP Key-chainSerial0/0 2 2 Yes xiaLoopback0 2 2Automatic network summarization is in effectMaximum path: 4Routing for Networks:1.0.0.0192.168.1.0Routing Information Sources:Gateway Distance Last Update192.168.1.2 120 00:00:19Distance: (default is 120)R1#注：由上面的“Serial0/0 2 2 Yes xia”表明已经在上Serial0/0启用了触发更新。R2#show ip rip datR2#show ip rip database1.0.0.0/8 auto-summary1.0.0.0/81 via 192.168.1.1, 00:02:48 (permanent), Serial0/0* Triggered Routes:- 1 via 192.168.1.1, Serial0/0192.168.1.0/24 auto-summary192.168.1.0/24 directly connected, Serial0/0192.168.2.0/24 auto-summary192.168.2.0/24 directly connected, Serial0/1192.168.3.0/24 auto-summary192.168.3.0/241 via 192.168.2.2, 00:01:13 (permanent), Serial0/1* Triggered Routes:- 1 via 192.168.2.2, Serial0/1R2#注：从路由器R2的rip数据值可以进一步的看出，在Serial0/0和Serial0/1启用了触发更新。如果想启用MD5认证，只要在接口下声明模式为MD5即可，具体配置命令如下：R1(config-keych
