第4章 OSPF协议

1.R1配置单区域OSPF

[R1]ospf 1 router-id 1.1.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 1.1.1.1 0.0.0.0
[R1-ospf-1-area-0.0.0.0]network 12.1.1.0 0.255.255.255

2.R2配置单区域OSPF

[R2]ospf 1 router-id 2.2.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0 
[R2-ospf-1-area-0.0.0.0]network 12.1.1.0 0.255.255.255
[R2-ospf-1-area-0.0.0.0]network 23.1.1.0 0.255.255.255

3.R3配置单区域OSPF

[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0
[R3-ospf-1-area-0.0.0.0]network 23.1.1.0 0.255.255.255

4.查看OSPF路由表

[R1]display ip routing-table protocol ospf 
 2.2.2.2/32  OSPF    10   1           D   12.1.1.2        GigabitEthernet0/0/0
        3.3.3.3/32  OSPF    10   2           D   12.1.1.2        GigabitEthernet0/0/0
       23.0.0.0/8   OSPF    10   2           D   12.1.1.2        GigabitEthernet0/0/0

[R2]display ip routing-table protocol ospf    
 1.1.1.1/32  OSPF    10   1           D   12.1.1.1        GigabitEthernet0/0/0
        3.3.3.3/32  OSPF    10   1           D   23.1.1.3        GigabitEthernet0/0/1

[R3]display ip routing-table protocol ospf    
 1.1.1.1/32  OSPF    10   2           D   23.1.1.2        GigabitEthernet0/0/1
        2.2.2.2/32  OSPF    10   1           D   23.1.1.2        GigabitEthernet0/0/1
       12.0.0.0/8   OSPF    10   2           D   23.1.1.2        GigabitEthernet0/0/1

5.查看OSPF路由运行信息

[R1]display ospf brief
         OSPF Process 1 with Router ID 1.1.1.1
                 OSPF Protocol Information
 RouterID: 1.1.1.1          Border Router: 
 Area: 0.0.0.0          (MPLS TE not enabled)

6.查看OSPF路由运行信息

[R1]display ospf brief
         OSPF Process 1 with Router ID 1.1.1.1
                 OSPF Protocol Information
 RouterID: 1.1.1.1          Border Router: 
 Area: 0.0.0.0          (MPLS TE not enabled)

7.查看邻居关系

[R1]display ospf peer brief 
 Area Id          Interface                        Neighbor id      State    
 0.0.0.0          GigabitEthernet0/0/0             2.2.2.2          Full     

8.查看详细路由信息

[R1]display ospf  lsdb router 3.3.3.3
