2实现和校验 EIGRP

配置EIGRP实现和验证EIGRProutereigrpautonomous-system-number•定义EIGRP作为路由协议.•所有网络中的路由器要交流路由更新，必需用相同的AS号.配置EIGRPnetworknetwork-number[wildcard-mask]•通告共享在EIGRP中的网段.•wildcard-mask是反掩码.用来确定如何解释地址。掩码具有通配符位，0表示要匹配1可以忽略Router(config)#Router(config-router)#bandwidthkilobits•定义接口带宽以供路由更新提供参数.配置EIGRPRouter(config-if)#因为路由器A并没有直连192.168.1.0网络，所以在路由器A上，网络192.168.1.0没有配置.配置IP的EIGRP在EIGRP上使用反掩码在EIGRP下使用和配置ipdefault-networkCommandEIGRP配置例子R2EIGRPConfigurationoutputomittedinterfaceFastEthernet0/0ipaddress172.17.2.2255.255.255.0outputomittedinterfaceSerial0/0/1bandwidth64ipaddress192.168.1.102255.255.255.224outputomittedroutereigrp100network172.17.2.00.0.0.255network192.168.1.0验证EIGRP:showipeigrpneighborsR1#showipeigrpneighborsIP-EIGRPneighborsforprocess100HAddressInterfaceHoldUptimeSRTTRTOQSeq(sec)(ms)CntNum0192.168.1.102Se0/0/11000:07:2210228005R1#H：序号Address：邻居地址Interface：接口Hold(sec):保持时间（秒）Uptime：上线时间SRTT（ms）：平滑往返时间RTO：重传超时时间QCnt：队列中的数目SeqNum:序列号验证EIGRP:showiprouteeigrpR1#showiprouteeigrpD172.17.0.0/16[90/40514560]via192.168.1.102,00:07:01,Serial0/0/1172.16.0.0/16isvariablysubnetted,2subnets,2masksD172.16.0.0/16isasummary,00:05:13,Null0192.168.1.0/24isvariablysubnetted,2subnets,2masksD192.168.1.0/24isasummary,00:05:13,Null0R1#showiprouteoutputomittedGatewayoflastresortisnotsetD172.17.0.0/16[90/40514560]via192.168.1.102,00:06:55,Serial0/0/1172.16.0.0/16isvariablysubnetted,2subnets,2masksD172.16.0.0/16isasummary,00:05:07,Null0C172.16.1.0/24isdirectlyconnected,FastEthernet0/0192.168.1.0/24isvariablysubnetted,2subnets,2masksC192.168.1.96/27isdirectlyconnected,Serial0/0/1D192.168.1.0/24isasummary,00:05:07,Null0验证EIGRP:showipprotocolsR1#showipprotocolsRoutingProtocolis“eigrp100“路由协议是EIGRP100，所以接口出去的更新过滤列表OutgoingupdatefilterlistforallinterfacesisnotsetIncomingupdatefilterlistforallinterfacesisnotsetDefaultnetworksflaggedinoutgoingupdates所以接口没有配置流入的更新过滤列表DefaultnetworksacceptedfromincomingupdatesEIGRPmetricweightK1=1,K2=0,K3=1,K4=0,K5=0EIGRP度量值权重EIGRPmaximumhopcount100EIGRP最大跳数为100EIGRPmaximummetricvariance1EIGRP最大度量值的变异数为1Redistributing:eigrp100重分布，EIGRP100EIGRPNSF-awarerouteholdtimeris240sEIGRP不间断转发（NSF）路由维持时间是240soutputomittedMaximumpath:4最大路径数4RoutingforNetworks:正在路由的网络172.16.1.0/24192.168.1.0RoutingInformationSources:路由信息的源GatewayDistanceLastUpdate网关管理距离最后更新(thisrouter)9000:09:38GatewayDistanceLastUpdate192.168.1.1029000:09:40Distance:internal90external170管理距离内部90外部170验证EIGRP:showipeigrpinterfacesR1#showipeigrpinterfacesIP-EIGRPinterfacesforprocess100XmitQueueMeanPacingTimeMulticastPendingInterfacePeersUn/ReliableSRTTUn/ReliableFlowTimerRoutesFa0/000/000/1000Se0/0/110/01010/3804240Interface：接口Peers：邻居数XmitQueueUn/Reliable：队列中可靠和不可靠的数目MeanSRTT:平均往返时间PacingTimeUn/Reliable：可靠和不可靠包准备传递时间MulticastFlowTimer:发送多播包的最大时间PendingRouters:将要被发送的路由条目验证EIGRP:showipeigrptopologyR1#showipeigrptopologyEIGRP拓扑表IP-EIGRPTopologyTableforAS(100)/ID(192.168.1.101)Codes:P-Passive,A-Active,U-Update,Q-Query,R-Reply,P-被动，A－主动，U－更新。Q－查询，R－回复，r-回复状态，s－陷入主动状态r-replyStatus,s-siaStatusP192.168.1.96/27,1successors,FDis40512000viaConnected,Serial0/0/1P192.168.1.0/24,1successors,FDis40512000viaSummary(40512000/0),Null0P172.16.0.0/16,1successors,FDis28160viaSummary(28160/0),Null0P172.16.1.0/24,1successors,FDis28160viaConnected,FastEthernet0/0P172.17.0.0/16,1successors,FDis40514560via192.168.1.102(40514560/28160),Serial0/0/1验证EIGRP:showipeigrptrafficR1#showipeigrptrafficIP-EIGRPTrafficStatisticsforAS100AS100EIGRP传输情况Hellossent/received:429/192Hellos发送/接收429/192Updatessent/received:4/4Updates发送/接收4/4Queriessent/received:1/0Repliessent/received:0/1Ackssent/received:4/3Inputqueuehighwatermark1,0dropsSIA-Queriessent/received:0/0SIA-Repliessent/received:0/0HelloProcessID:113PDMProcessID:73总结•基本的EIGRP配置包括:–routereigrpautonomous-system–networknetwork-number[wildcard-mask]–bandwidthkilobits•Network命令中可选的wildcard-mask参数是反掩码.0表示要匹配1表示不关心。•使用ipdefault-networknetwork-number命令创建和通过一条缺省路由进入EIGRP自治系统。总结•showipeigrpneighbors命令用于检查eigrp邻居关系•showiprouteeigrp命令用于检查从邻居那里学来的路由.•showipprotocols,showipeigrpinterfaces,showipeigrpneighbors,showipeigrptopology,和showipeigrptraffic命令用于检查eigrp的状态.
