1、一、搭建本次实验的拓扑结构
三台路由器、一台交换机
2、二、配置设备的接口信息
<R1>system-view Enter system view, return user view with Ctrl+Z. [R1]interface GigabitEthernet 0/0/0 [R1-GigabitEthernet0/0/0]ip address 10.0.123.1 24 [R1-GigabitEthernet0/0/0]quit [R1]interface LoopBack 0 [R1-LoopBack0]ip address 10.0.1.1 24 [R1-LoopBack0]quit <R2>system-view Enter system view, return user view with Ctrl+Z. [R2]interface GigabitEthernet 0/0/0 [R2-GigabitEthernet0/0/0]ip address 10.0.123.2 24 [R2-GigabitEthernet0/0/0]quit [R2]interface LoopBack 0 [R2-LoopBack0]ip address 10.0.2.2 24 [R2-LoopBack0]quit <R3>system-view Enter system view, return user view with Ctrl+Z. [R3]interface GigabitEthernet 0/0/0 [R3-GigabitEthernet0/0/0]ip address 10.0.123.3 24 [R3-GigabitEthernet0/0/0]quit [R3]interface LoopBack 0 [R3-LoopBack0]ip address 10.0.3.3 24 [R3-LoopBack0]quit
3、三、测试区域内的网络连通性
<R1>ping -c 1 10.0.123.2 PING 10.0.123.2: 56 data bytes, press CTRL_C to break Reply from 10.0.123.2: bytes=56 Sequence=1 ttl=255 time=70 ms
--- 10.0.123.2 ping statistics --- 1 packet(s) transmitted 1 packet(s) received 0.00% packet loss round-trip min/avg/max = 70/70/70 ms
<R1>ping -c 1 10.0.123.3 PING 10.0.123.3: 56 data bytes, press CTRL_C to break Reply from 10.0.123.3: bytes=56 Sequence=1 ttl=255 time=50 ms
--- 10.0.123.3 ping statistics --- 1 packet(s) transmitted 1 packet(s) received 0.00% packet loss round-trip min/avg/max = 50/50/50 ms
4、四、配置单区域的OSPF，并同时配置区域认证
[R1]ospf 1 router-id 10.0.1.1
[R1-ospf-1]area 0 [R1-ospf-1-area-0.0.0.0]network 10.0.123.1 0.0.0.0 [R1-ospf-1-area-0.0.0.0]network 10.0.1.1 0.0.0.0 [R1-ospf-1-area-0.0.0.0]authentication-mode simple plain huawei [R2]ospf 1 router-id 10.0.2.2 [R2-ospf-1]area 0 [R2-ospf-1-area-0.0.0.0]network 10.0.123.2 0.0.0.0 [R2-ospf-1-area-0.0.0.0]network 10.0.2.2 0.0.0.0 [R2-ospf-1-area-0.0.0.0]authentication-mode simple plain huawei [R3]ospf 1 router-id 10.0.3.3 [R3-ospf-1]area 0 [R3-ospf-1-area-0.0.0.0]network 10.0.123.3 0.0.0.0 [R3-ospf-1-area-0.0.0.0]network 10.0.3.3 0.0.0.0 [R3-ospf-1-area-0.0.0.0]authentication-mode simple plain huawei
5、五、查看配置完成后的路由表
<R1>dis ip rou Route Flags: R - relay, D - download to fib------------------------------------------------------------------------------Routing Tables: Public Destinations : 12 Routes : 12
Destination/Mask Proto Pre Cost Flags NextHop Interface
10.0.1.0/24 Direct 0 0 D 10.0.1.1 LoopBack0 10.0.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack0 10.0.1.255/32 Direct 0 0 D 127.0.0.1 LoopBack0 10.0.2.2/32 OSPF 10 1 D 10.0.123.2 GigabitEthernet0/0/0 10.0.3.3/32 OSPF 10 1 D 10.0.123.3 GigabitEthernet0/0/0 10.0.123.0/24 Direct 0 0 D 10.0.123.1 GigabitEthernet0/0/0 10.0.123.1/32 Direct 0 0 D 127.0.0.1 GigabitEthernet0/0/0 10.0.123.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet0/0/0 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
6、六、 测试配置完成后的网络连通性<R1>ping -c 1 10.0.2.2 PING 10.0.2.2: 56 data bytes, press CTRL_C to break Reply from 10.0.2.2: bytes=56 Sequence=1 ttl=255 time=70 ms
--- 10.0.2.2 ping statistics --- 1 packet(s) transmitted 1 packet(s) received 0.00% packet loss round-trip min/avg/max = 70/70/70 ms
<R1>ping -c 1 10.0.3.3 PING 10.0.3.3: 56 data bytes, press CTRL_C to break Reply from 10.0.3.3: bytes=56 Sequence=1 ttl=255 time=40 ms
--- 10.0.3.3 ping statistics --- 1 packet(s) transmitted 1 packet(s) received 0.00% packet loss round-trip min/avg/max = 40/40/40 ms
7、七、观察OSPF的生成情况
配置的区域认证为简单认证，通过认证保证了区域内的设备通信
