拓扑结构表明：R1、R2在地区1内，R2、R3在地区0内，R3、R4在地区2内。R2、R3为ABR地区界限无线路由器。试验目地：1，如何开展多地区下OSPF配备2，如何区别不一样地区下的路由器3，怎样根据路由器归纳来降低在OSPF中单由内容
www. 针对R1、R2、R3、R4在无线路由器中的配备请参照配件：1，在R2上查询OSPF隔壁邻居表：R2#show ip ospf neNeighbor ID Pri State Dead Time Address Interface192.168.1.9 0 FULL/- 00:00:33 192.168.1.6 Serial1/110.1.2.1 0 FULL/- 00:00:32 192.168.1.1 Serial1/0表明R1和R3早已创建了隔壁邻居关联
www. 2，在R2上查看路由表：R2#show ip routeCodes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static routeGateway of last resort is not set 172.16.0.0/32 is subnetted, 2 subnetsO IA 172.16.1.1 [110/129] via 192.168.1.6, 00:26:33, Serial1/1O IA 172.16.2.1 [110/129] via 192.168.1.6, 00:26:33, Serial1/1 10.0.0.0/32 is subnetted, 2 subnetsO 10.1.2.1 [110/65] via 192.168.1.1, 00:26:43, Serial1/0O 10.1.1.1 [110/65] via 192.168.1.1, 00:26:43, Serial1/0 192.168.1.0/30 is subnetted, 3 subnetsO IA 192.168.1.8 [110/128] via 192.168.1.6, 00:26:33, Serial1/1C 192.168.1.0 is directly connected, Serial1/0C 192.168.1.4 is directly connected, Serial1/1O IA表明其他地区的路由器；O表明地区内路由器；C表明与无线路由器直联网段[110/128]110表明OSPF管理方法间距，128表明COST值针对路由器选路时不一样路由协议首选管理方法间距小的，相同路由协议首选COST值小的。3．查询R3上的链接情况数据库查询： www.
