OSPF学习配置： Stub 区域配置

-----------R3配置--------------------

Router>en
Router#config
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line.   End with CNTL/Z.
Router(config)#ho R1
R3(config)#NO IP Domain-lo
R3(config)#line c 0
R3(config-line)#logg syn
R3(config-line)#exec-t 0 0
R3(config-line)#exit
R3(config)#int ser1
R3(config-if)#ip add 10.0.0.6 255.255.255.252
R3(config-if)#no shut
R3(config-if)#exit
R3(config)#int lo 0
R3(config-if)#ip add 172.17.1.1 255.255.255.0
R3(config)#router ospf 100
R3(config-router)#net 10.0.0.4 0.0.0.3 area 2
(这里的S1与E0属于区域0，即在ABR上)
R3(config-router)#net 172.17.1.0 0.0.0.255 area 2
R3(config-router)#area 2 stub
R2(config-router)#area 2 authentication message-digest
R3(config-router)#exit
R3(config)#int ser1
R3(config-if)#ip ospf message-digest-key 1 md5 huawei
R3(config-if)#no shut
R3(config-if)#exit
R3(config)#

------------------验证过程-------------
R2#sh ip route
Codes: C - connected, S - static, I - IGRP, 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, E - EGP
        i - IS-IS, 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 route
Gateway of last resort is 100.1.1.1 to network 0.0.0.0
      100.0.0.0/30 is subnetted, 1 subnets
C        100.1.1.0 is directly connected, Ethernet0
      10.0.0.0/30 is subnetted, 1 subnets
C        10.0.0.4 is directly connected, Serial1
O*IA 0.0.0.0/0 [110/11] via 100.1.1.1, 00:00:43, Ethernet0
(这里就一条静态路由了，干掉了L3)
