配置OSPF基本功能示例

配置OSPF基本功能示例介绍OSPF基本功能的配置过程，包括在各路由器上使能OSPF、指定不同区域内的网段。组网需求如图1所示，全部的路由器都运行OSPF,并将整个自治系统划分为三个区域，其中RouterA和RouterB作为ABR来转发区域之间的路由。配置完成后，每台路由器都应学到AS内的到全部网段的路由。1配置OSPF基本功能组网图4桌/RouterAjgy/ POS2/0/0|^AreaO、、、、posi/o/6\POS1/0/0Vl92.168.0.1/24POS1/0/0RouterCGE2/0/0GE2/0/0RouterERouterDRouterB\POS2/0/0 \192.168.2.1/24\；GE2/0/0 ,\^^/二.JRouterF\Areal\Area2配置思路Sum-Net222.22032880000001Sum-Net2372880000002Sum-Net2952880000002TypeLinkStateIDAdvRouterAgeLenSequenceMetricRouter2143680000004Router2176080000008Router2894880000002Network6703280000001Sum-Net2022880000001Sum-Net2422880000001Sum-Net3002880000001[RouterD]displayospfroutingRoutingTablesRoutingforNetworkAdvRouterDestinationCostTypeNextHopAreaAdvRouterTotalNets:5IntraArea:2InterArea:3ASE:0NSSA:0PING172.16.1.1:56databytes,pressCTRL_CtobreakReplyfrom172.16.1.1:bytes=56Sequence=lttl=253time=62msReplyfrom172.16.1.1:bytes=56Sequence=2ttl=253time=16msReplyfrom172.16.1.1:bytes=56Sequence=3ttl=253time=62msReplyfrom172.16.1.1:bytes=56Sequence=4ttl=253time=94msReplyfrom172.16.1.1:bytes=56Sequence=5ttl=253time=63ms—172.16.1.1pingstatistics—5packet(s)transmitted5packet(s)received0.00%packetlossround-tripmin/avg/max=16/59/94ms配置文件sysnameRouterA##interfacePos1/0/0link-protocolpppundoshutdown#interfacePos2/0/0Iink-protocolpppundoshutdownospf1#return.RouterB的配置文件#sysnameRouterBinterfacePos1/0/0Iink-protocolpppundoshutdown#interfacePos2/0/0Iink-protocolpppundoshutdown#ospf1#return•RouterC的配置文件sysnameRouterC##interfaceGigabitEthernet2/0/0undoshutdown#interfacePos1/0/0Iink-protocolpppundoshutdown#ospf1return•RouterD的配置文件#sysnameRouterD##interfaceGigabitEthernet2/0/0undoshutdown#interfacePos1/0/0Iink-protocolpppundoshutdown#ospf1#return・RouterE的配置文件#sysnameRouterE采纳如下的思路配置OSPF基本功能:.在各路由器上使能OSPFo.指定不同区域内的网段。数据预备为完成此配置例，需预备如下的数据：RouterA的routerid1.1.1.1,运行的OSPF进程号1,在区域0的网段,在区域1的网段。RouterB的routerid2.2.2.2,运行的OSPF进程号1,在区域0的网段,在区域2的网段192.16820/24。RouterC的routerid3.3.33,运行的OSPF进程号1,在区域1的网段,oRouterD的routerid4.4.4.4,运行的OSPF进程号1,在区域2的网段,172.17.1.0/24。口0仇6出的「0仇6封（^运行的OSPF进程号1在区域1的网段172.16.1.0/24。.RouterF的routerid6.6.6.6运行的OSPF进程号1在区域2的网段172.17.1.0/24。#interfaceGigabitEthernet2/0/0undoshutdown#ospf1#return•RouterF的配置文件sysnameRouterF##interfaceGigabitEthernet2/0/0undoshutdown#ospf1#return操作步骤.配置各接口的IP地址（略）.配置OSPF基本功能配置RouterAo[Route[RouterA]ospf[RouterA-ospf-1]area0[RouterA-ospf-l-area-0.0.0.0][RouterA-ospf-l-area-0.0.0.0]quit[RouterA-ospf-1]area1[RouterA-ospf-l-area-0.0.0.1][RouterA-ospf-l-area-0.0.0.1]quit配置RouterBo[RouterB][RouterB]ospf[RouterB-ospf-1]area0[RouterB-ospf-l-area-0.0.0.0][RouterB-ospf-l-area-0.0.0.0]quit[RouterB-ospf-1]area2[RouterB-ospf-l-area-0.0.0.2][RouterB-ospf-l-area-0.0.0.2]quit配置RouterCo[RouterC][RouterC]ospf[RouterC-ospf-1]area1[RouterC-ospf-l-area-0.0.0.1][RouterC-ospf-l-area-0.0.0.1][RouterC-ospf-l-area-0.0.0.1]quit配置RouterDo[RouterD][RouterD]ospf[RouterD-ospf-1]area2[RouterD-ospf-l-area-0.0.0.2][RouterD-ospf-l-area-0.0.0.2][RouterD-ospf-l-area-0.0.0.2]quit配置RouterEo[RouterE][RouterE]ospf[RouterE-ospf-1]area1[RouterE-ospf-l-area-0.0.0.1][RouterE-ospf-l-area-0.0.0.1]quit配置RouterFo[RouterF][RouterF]ospf[RouterF-ospf-1]area2[RouterF-ospf-l-area-0.0.0.2][RouterF-ospf-l-area-0.0.0.2]quit3.验证配置结果#查看RouterA的OSPF邻居。[RouterA]displayospfpeerNeighborsArea0.0.0.0interface192.168.0.1(Posl/0/0)'sneighborsState:FullMode:NbrisMasterPriority:1DR:NoneBDR:NoneMTU:0Deadtimerduein36secRetranstimerinterval:5Neighborisupfor00:15:04AuthenticationSequence:[0]NeighborsArea0.0.0.1interface192.168.1.1(Pos2/0/0)'sneighborsState:FullMode:NbrisMasterPriority:1DR:NoneBDR:NoneMTU:0Deadtimerduein39secRetranstimerinterval:5Neighborisupfor00:07:32AuthenticationSequence:[0]#显示RouterA的OSPF路由信息。[RouterA]displayospfroutingRoutingTablesRoutingforNetworkDestinationCostType NextHop AdvRouterAreaTotalNets:5IntraArea:3InterArea
