新版BSCI实验手册-配置ospf验证

新版BSCI实验手册-配置ospf验证，汇总，虚链路 环境：三台路由器串口相连，其它接口配置如图

要求：1.在area 1配置ospf虚链路,router-id如图配置

2.将R1的LOOP口配置ospf手工路由汇总

3.

配置ospf接口验证（R1 和R2）

4.使用show命令查看结果

步骤一： 配置三个路由器接口使其连通。

R1的配置

R1(config)# interface Loopback0

R1(config-if)# ip address 30.1.1.1 255.255.255.0

R1(config)# interface Loopback1

R1(config-if)# ip address 30.1.2.1 255.255.255.0

R1(config)# interface Loopback2

R1(config-if)# ip address 30.1.3.1 255.255.255.0

R1(config)# interface s0

R1(config-if)# ip address 10.1.1.1 255.255.255.0

R1(config-if)#no shutdown

R2的配置

R2(config)# interface Loopback0

R2(config-if)# ip address 50.1.1.1 255.255.255.0

R2(config)# interface s0

R2(config-if)# ip address 10.1.1.2 255.255.255.0

R2(config-if)#clockrate 64000

R2(config-if)#no shutdown

R2(config)# interface s1

新版BSCI实验手册-配置ospf验证

R2(config-if)# ip address 20.1.1.1 255.255.255.0

R2(config-if)#no shutdown

R3的配置

R3(config)# interface Loopback0

R3(config-if)# ip address 40.1.1.1 255.255.255.0

R3(config)# interface s1

R3(config-if)# ip address 20.1.1.2 255.255.255.0

R3(config-if)#clockrate 64000

R3(config)#no shutdown

步骤二： 配置ospf

R1的配置

R1(config)#router ospf 1

启用ospf协议，进程号为1

R1(config-router)#router-id 1.1.1.1

配置router-id

R1(config-router)#network 10.1.1.0 0.0.0.255 area 1

将接口参与到区域1内

R1(config-router)#network 30.1.1.0 0.0.0.255 area 0

将接口参与到区域0内

R1(config-router)#network 30.1.2.0 0.0.0.255 area 0

R1(config-router)#network 30.1.3.0 0.0.0.255 area 0

R2的配置

R2(config)#router ospf 1

R2(config-router)#router-id 2.2.2.2

R2(config-router)#network 10.1.1.0 0.0.0.255 area 1

R2(config-router)#network 20.1.1.0 0.0.0.255 area 2

将接口参与到区域2内

R2(config-router)#network 50.1.1.0 0.0.0.255 area 1

R3的配置

R3(config)#router ospf 2

R3(config-router)#router-id 3.3.3.3

R3(config-router)#network 20.1.1.0 0.0.0.255 area 2

R3(config-router)#network 40.1.1.0 0.0.0.255 area 2

步骤三：配置ospf虚链路

R1的配置

新版BSCI实验手册-配置ospf验证

R1(config)#router ospf 1

R1(config-router)# area 1 virtual-link 2.2.2.2 配置虚电路,指对端的router-id

R2的配置

R2(config)#router ospf 1

R2(config-router)# area 1 virtual-link 1.1.1.1

步骤四：配置ospf手工路由汇总

R1的配置

R1(config)#router ospf 1

R1(config-router)# area 0 range 30.1.0.0 255.255.252.0

手工汇总路由

R2的配置

R2(config)#router ospf 1

R2(config-router)# area 0 range 30.1.0.0 255.255.252.0

因你的区域0已经延伸到此

步骤五：配置ospf接口验证（R1 和R2）

R1的配置

R1(config)# interface Serial0

R1(config-if)# ip ospf authentication message-digest

启用验证

R1(config-if)# ip ospf message-digest-key 1 md5 cisco 定义密钥

R2的配置

R2(config)# interface Serial0

R2(config-if)# ip ospf authentication message-digest

R2(config-if)# ip ospf message-digest-key 1 md5 cisco

两端必须一致

步骤六：查看路由表
