chp25路由优化-251被动接口和分布列表实验指导

被动接口和分布列表配置通过本实验可以掌握：控制路由更新的技术被动接口对不同路由协议的影响分布列表控制路由更新被动接口的配置分布列表的配置实验拓扑如图所示。将R1和R3的环回接口配置为被动接口。配置分布列表，要求如下：R1发送EIGRP更新时，过滤172.16.X.0路由,其中X为奇数的路由条目过滤（1）配置路由器R1R1(config)#interfaceLoopback0R1(config-if)#exitR1(config)#interfaceLoopback1R1(config-if)#exitR1(config)#interfaceLoopback2R1(config-if)#exitR1(config)#interfaceLoopback3R1(config-if)#exitR1(config)#interfaceLoopback4R1(config-if)#exitR1(config)#interfaceLoopback5R1(config-if)#exitR1(config)#interfaceLoopback6R1(config-if)#exitR1(config)#interfaceLoopback7R1(config-if)#exitR1(config)#interfaceLoopback8R1(config-if)#exitR1(config)#interfaceLoopback9R1(config-if)#exitR1(config)#interfaceLoopback10R1(config-if)#exitR1(config)#interfaceLoopback11R1(config-if)#exitR1(config)#interfaceLoopback12R1(config-if)#exitR1(config)#interfaceLoopback33R1(config-if)#exitR1(config)#interfaceLoopback188R1(config-if)#exitR1(config)#interfaceLoopback199R1(config-if)#exitR1(config)#interfaceLoopback200R1(config-if)#exitR1(config)#interfaceSerial0/0R1(config-if)#clockrate128000R1(config-if)#noshutR1(config-if)#exitR1(config)#access-list1permitanyR1(config)#routereigrp1R1(config-router)#passive-interfacedefaultR1(config-router)#nopassive-interfaceSerial0/0R1(config-router)#network172.31.1.1.0R1(config-router)#network172.31.12.1.0R1(config-router)#distribute-list1outSerial0/0R1(config-router)#noauto-summary（2）配置路由器R2R2(config)#interfaceSerial0/0R2(config-if)#noshutR2(config-if)#exitR2(config)#interfaceSerial0/1R2(config-if)#clockrate128000R2(config-if)#noshutR2(config-if)#exitR2(config)#routereigrp1R2(config-router)#redistributeospf1metric100010025511500R2(config-router)#network172.31.12.2.0R2(config-router)#auto-summaryR2(config-router)#exitR2(config)#routerospf1R2(config-router)#router-id.2R2(config-router)#redistributeeigrp1subnetsR2(config-router)#network172.31.23.2.0area0R2(config-router)#distribute-list2outeigrp1（3）配置路由器R3R3(config)#interfaceLoopback0R3(config-if)#exitR3(config)#interfaceSerial0/1R3(config-if)#noshutR3(config-if)#exitR3(config)#routerospf1R3(config-router)#router-id.3R3(config-router)#network172.31.3.3.0area0R3(config-router)#network172.31.23.3.0area0R3(config-router)#distribute-list1inSerial0/14.实验调试R1#shipprotocolsRoutingProtocolis"eigrp1"OutgoingupdatefilterlistforallinterfacesisnotsetSerial0/0filteredby1,defaultis1IncomingupdatefilterlistforallinterfacesisnotsetDefaultnetworksflaggedinoutgoingupdatesDefaultnetworksacceptedfromincomingupdatesEIGRPmetricweightK1=1,K2=0,K3=1,K4=0,K5=0EIGRPmaximumhopcount100EIGRPmaximummetricvariance1Redistributing:eigrp1EIGRPNSF-awarerouteholdtimeris240sAutomaticnetworksummarizationisnotineffectMaximumpath:4RoutingforNetworks:PassiveInterface(s):Serial0/1Serial0/2Serial0/3Loopback0Loopback1PassiveInterface(s):Loopback2Loopback3Loopback4Loopback5Loopback6Loopback7Loopback8Loopback9Loopback10Loopback11Loopback12Loopback33Loopback188Loopback199Loopback200VoIP-Null0RoutingInformationSources:GatewayDistanceLastUpdate172.31.12.29000:03:38Distance:internal90external170R2#shiprouteCodes:C-connected,S-static,R-RIP,M-mobile,B-BGPD-EIGRP,EX-EIGRPexternal,O-OSPF,IA-OSPFinterareaN1-OSPFNSSAexternaltype1,N2-OSPFNSSAexternaltype2E1-OSPFexternaltype1,E2-OSPFexternaltype2i-IS-IS,su-IS-ISsummary,L1-IS-ISlevel-1,L2-IS-ISlevel-2ia-IS-ISinterarea,*-candidatedefault,U-per-userstaticrouteo-ODR,P-periodicdownloadedstaticrouteGatewayoflastresortisnotset172.16.0.0/24issubnetted,9subnetsD172.16.188.0[90/2297856]via172.31.12.1,00:04:18,Serial0/0D172.16.200.0[90/2297856]via172.31.12.1,00:04:18,Serial0/0D172.16.12.0[90/2297856]via172.31.12.1,00:04:18,Serial0/0D172.16.8.0[90/2297856]via172.31.12.1,00:04:18,Serial0/0D172.16.10.0[90/2297856]via172.31.12.1,00:04:18,Serial0/0D172.16.4.0[90/2297856]via172.31.12.1,00:04:19,Serial0/0D172.16.6.0[90/2297856]via172.31.12.1,00:04:19,Serial0/0D172.16.0.0[90/2297856]via172.31.12.1,00:04:19,Serial0/0D172.16.2.0[90/2297856]via172.31.12.1,00:04:19,Serial0/0172.31.0.0/16isvariablysubnetted,4subnets,2masksC172.31.23.0/24isdirectlyconnected,Serial0/1D172.31.1.0/24[90/2297856]via172.31.12.1,00:04:19,Serial0/0O172.31.3.3/32[110/65]via172.31.23.3,00:11:13,Serial0/1C172.31.12.0/24isdirectlyconnected,Serial0/0R2#showipprotocolsRoutingProtocolis"eigrp1"OutgoingupdatefilterlistforallinterfacesisnotsetIncomingupdatefilterlistforallinterfacesisnotsetDefaultnetworksflaggedinoutgoingupdatesDefaultnetworksacceptedfromincomingupdatesEIGRPmetricweightK1=1,K2=0,K3=1,K4=0,K5=0EIGRPmaximumhopcount100EIGRPmaximummetricvariance1Redistributing:eigrp1,ospf1EIGRPNSF-awarerouteholdtimeris240sAutomaticnetworksummarizationisineffectMaximumpath:4RoutingforNetworks:RoutingInformationSources:GatewayDistanceLastUpdate172.31.12.19000:04:27Distance:internal90external170RoutingProtocolis"ospf1"OutgoingupdatefilterlistforallinterfacesisnotsetRedistributedeigrp1filteredby2IncomingupdatefilterlistforallinterfacesisnotsetRouterID.2ItisanautonomoussystemboundaryrouterRedistributingExternalRoutesfrom,eigrp1,includessubnetsinredistributionNumberofareasinth
