OSPF Stub TotallyStub 区域配置.doc

OSPF Stub、Totally Stubby区域配置【实验名称】 OSPF Stub、Totally Stubby区域配置【实验目的】 掌握OSPF各种类型区域的配置技术。【背景描述】 你是一名高级技术网络工程师，某企业的网络整个的网络环境是ospf。为了减少路有表的条目，提高路由器工作效率，需要配置不同的区域属性。【实现功能】 通过对区域属性的定义，减少路有表的条目，提高路由器工作效率。【实验拓扑】 【实验设备】 R2624路由器（3台）、V35DCE（2根）、V35DTE（2根）【实验步骤】 第一步：基本配置Red-Giantenable Red-Giant#conf tRed-Giant(config)#hostname R1R1(config)#int serial 0R1(config-if)#ip add 192.168.12.1 255.255.255.0R1(config-if)#cl ra 64000R1(config-if)# no shR1(config-if)#exiR1(config)#int loo 0R1(config-if)#ip add 1.1.1.1 255.255.255.0Red-Giant#configure terminal Red-Giant(config)#hostname R2R2(config)#interface serial 0R2(config-if)#ip address 192.168.12.2 255.255.255.0R2(config-if)#no shutdown R2(config-if)#exiR2(config)#interface serial 1R2(config-if)#ip address 192.168.23.2 255.255.255.0R2(config-if)#clock rate 64000R2(config-if)#no shutdownRed-Giant#conf tRed-Giant(config)#hos R3R3(config)#int s0R3(config-if)#ip add 192.168.23.3 255.255.255.0R3(config-if)#ino shR3(config-if)#end验证测试： R3#ping 192.168.23.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echoes to 192.168.23.2, timeout is 2 seconds:!R1#ping 192.168.12.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echoes to 192.168.12.2, timeout is 2 seconds:!第二步：配置路由协议 OSPFR1(config)#router os 1R1(config-router)#net 192.168.12.0 0.0.0.255 area 0R1(config-router)#net 1.1.1.0 0.0.0.255 area 1R1(config-router)#endR2(config)#router ospf 1R2(config-router)#network 192.168.12.0 0.0.0.255 area 0R2(config-router)#net 192.168.23.0 0.0.0.255 area 2R3(config)#router os 1R3(config-router)#net 192.168.23.0 0.0.0.255 area 2验证测试：R3#sh ip ro 1.0.0.0/32 is subnetted, 1 subnetsO IA 1.1.1.1 110/97 via 192.168.23.2, 00:01:52, Serial0O IA 192.168.12.0/24 110/96 via 192.168.23.2, 00:01:52, Serial0C 192.168.23.0/24 is directly connected, Serial0第三步：配置完全末节区域R3(config)#router os 1R3(config-router)#area 2 stub ! 配置area 2 为末节区域R2(config)#router os 1R2(config-router)#area 2 stub no-summary ! 配置area 2 为完全末节区域验证测试：R3#sh ip roGateway of last resort is 192.168.23.2 to network 0.0.0.0C 192.168.23.0/24 is directly connected, Serial0O*IA 0.0.0.0/0 110/49 via 192.168.23.2, 00:15:15, Serial0【注意事项】l 只有在完全末节区域的路由器才能达到路由表最小化；l 末节区域的配置需要在其区域中所有路由器上配置。【参考配置】R3#sh runCurrent configuration:!version 6.14(2)!hostname R3!ip subnet-zerointerface FastEthernet0 no ip address!interface FastEthernet1 no ip address shutdown!interface FastEthernet2 no ip addressshutdown!interface FastEthernet3 no ip address shutdown!interface Serial0 ip address 192.168.23.3 255.255.255.0!interface Serial1 no ip address shutdown!router ospf 1 network 192.168.23.0 0.0.0.255 area 2 area 2 stub!ip classless!line con 0line aux 0line vty 0 4 no loginR2#sh runCurrent configuration:!version 6.14(2)!hostname R2!ip subnet-zero!interface FastEthernet0 no ip address shutdown!interface FastEthernet1 no ip address shutdown!interface FastEthernet2no ip address shutdown!interface FastEthernet3 no ip address shutdown!interface Serial0 ip address 192.168.12.2 255.255.255.0!interface Serial1 ip address 192.168.23.2 255.255.255.0 clock rate 64000!router ospf 1 network 192.168.12.0 0.0.0.255 area 0 network 192.168.23.0 0.0.0.255 area 2 area 2 stub no-summary!ip classless!line con 0line aux 0line vty 0 4 login!endR1#sh runCurrent configuration:!version 6.14(2)!hostname R1!ip subnet-zero!interface Loopback0 ip address 1.1.1.1 255.255.255.0!interface FastEthernet0 no ip address shutdown!interface FastEthernet1 no ip addressshutdown!interface FastEthernet2 no ip address shutdown!interface FastEthernet3 no ip address shutdown!interface Serial0 ip address 192.168.12.1 255.255.255.0 clock ra
