08级网络与开发方向实验报告——CCNA7-03EIGRP路由自动汇总姓名：张三日期：2010-9-7实验名称：EIGRP路由自动汇总试验目标：了解EIGRP协议自动汇总功能。在类的边界自动汇总。在不连续的网络禁止自动汇总实验环境：任务：在以上路由器上配置EIGRP协议。在不连续的地址禁用路由汇总步骤：1.在网络中配置EIGRP协议1.1在Router5、2、0、1上08级网络与开发方向实验报告——CCNARouter(config)#routeeigr10Router(config-router)#network172.16.0.01.2在Router4、3上Router(config)#routeeigr10Router(config-router)#network172.16.0.0Router(config-router)#network10.0.0.01.3在Router6上Router(config)#routeeigr10Router(config-router)#network10.0.0.02.查看路由汇总结果2.1在Router6上查看路由Router#showiprouteCodes:C-connected,S-static,I-IGRP,R-RIP,M-mobile,B-BGPD-EIGRP,EX-EIGRPexternal,O-OSPF,IA-OSPFinterareaN1-OSPFNSSAexternaltype1,N2-OSPFNSSAexternaltype2E1-OSPFexternaltype1,E2-OSPFexternaltype2,E-EGPi-IS-IS,L1-IS-ISlevel-1,L2-IS-ISlevel-2,ia-IS-ISinterarea*-candidatedefault,U-per-userstaticroute,o-ODRP-periodicdownloadedstaticrouteGatewayoflastresortisnotset10.0.0.0/24issubnetted,2subnetsC10.0.0.0isdirectlyconnected,Serial3/0C10.0.1.0isdirectlyconnected,Serial2/0D172.16.0.0/16[90/20514560]via10.0.0.1,00:14:03,Serial3/0[90/20514560]via10.0.1.2,00:13:41,Serial2/0Router#路由器看到到172.16.0.0/16网段有两条可用路由。这是错误的汇总。2.2在Router6上测试到PC0的连接Router#ping172.16.10.2Typeescapesequencetoabort.Sending5,100-byteICMPEchosto172.16.10.2,timeoutis2seconds:08级网络与开发方向实验报告——CCNA..!.!Successrateis40percent(2/5),round-tripmin/avg/max=13/14/15msRouter#ping172.16.10.2Typeescapesequencetoabort.Sending5,100-byteICMPEchosto172.16.10.2,timeoutis2seconds:.!.!.Successrateis40percent(2/5),round-tripmin/avg/max=14/16/19ms发现丢包。这是因为错误的路由汇总造成的。3.关闭EIGRP的自动汇总3.1在所有的路由器上运行以下命令Router(config)#routere10Router(config-router)#noauto-summary关闭自动汇总Router(config-router)#3.2在Router6上Router#showiprouteCodes:C-connected,S-static,I-IGRP,R-RIP,M-mobile,B-BGPD-EIGRP,EX-EIGRPexternal,O-OSPF,IA-OSPFinterareaN1-OSPFNSSAexternaltype1,N2-OSPFNSSAexternaltype2E1-OSPFexternaltype1,E2-OSPFexternaltype2,E-EGPi-IS-IS,L1-IS-ISlevel-1,L2-IS-ISlevel-2,ia-IS-ISinterarea*-candidatedefault,U-per-userstaticroute,o-ODRP-periodicdownloadedstaticrouteGatewayoflastresortisnotset10.0.0.0/8isvariablysubnetted,3subnets,2masksD10.0.0.0/8[90/21024000]via10.0.0.1,00:01:20,Serial3/0[90/21024000]via10.0.1.2,00:01:03,Serial2/0C10.0.0.0/24isdirectlyconnected,Serial3/0C10.0.1.0/24isdirectlyconnected,Serial2/0172.16.0.0/16isvariablysubnetted,11subnets,2masksD172.16.0.0/16isasummary,00:01:37,Null0D172.16.0.0/24[90/22050560]via10.0.1.2,00:00:07,Serial2/008级网络与开发方向实验报告——CCNAD172.16.1.0/24[90/22048000]via10.0.1.2,00:00:28,Serial2/0D172.16.2.0/24[90/21538560]via10.0.1.2,00:00:28,Serial2/0D172.16.3.0/24[90/21536000]via10.0.1.2,00:00:45,Serial2/0D172.16.4.0/24[90/21026560]via10.0.1.2,00:00:45,Serial2/0D172.16.5.0/24[90/21024000]via10.0.1.2,00:01:03,Serial2/0D172.16.6.0/24[90/20514560]via10.0.1.2,00:01:03,Serial2/0D172.16.8.0/24[90/20514560]via10.0.0.1,00:01:20,Serial3/0D172.16.9.0/24[90/21024000]via10.0.0.1,00:01:20,Serial3/0D172.16.10.0/24[90/21026560]via10.0.0.1,00:01:20,Serial3/0Router#ping172.16.0.2Typeescapesequencetoabort.Sending5,100-byteICMPEchosto172.16.0.2,timeoutis2seconds:.!!!!能够ping通172.16.0.0/24网段Successrateis80percent(4/5),round-tripmin/avg/max=17/23/27msRouter#ping172.16.10.2Typeescapesequencetoabort.Sending5,100-byteICMPEchosto172.16.10.2,timeoutis2seconds:.!!!!能够ping通172.16.10.0/24网段Successrateis80percent(4/5),round-tripmin/avg/max=14/16/20msRouter#可以看到关闭自动汇总后，在IP的类的边界不会自动汇总。Router6学到了到所有网段的路由信息。总结
