第1章 路由引入

1.1协议之间引入路由

1.R2配置OSPF

[R2]ospf 1 router-id 2.2.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 23.1.0 0.255.255.255

2.R3配置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

3.R3配置ISIS

[R3]isis 1
[R3-isis-1]network-entity 49.0034.0000.0000.0003.00
[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]isis enable 1

4.R4配置ISIS

[R4]isis 1
[R4-isis-1]network-entity 49.0034.0000.0000.0004.00
[R4]interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0]isis enable 1
[R4]interface LoopBack 0
[R4-LoopBack0]isis enable 1

5.R3在ISIS和OSPF相互引入

[R3]isis  1
[R3-isis-1]import-route ospf 1
[R3-isis-1]quit
[R3]ospf 1
[R3-ospf-1]import-route isis 1

6.R2查看OSPF路由表

<R2>display ip routing-table protocol ospf 
 3.3.3.3/32  OSPF    10   1           D   23.1.1.3        GigabitEthernet0/0/1
        4.4.4.4/32  O_ASE   150  1           D   23.1.1.3        GigabitEthernet0/0/1
       34.0.0.0/8   O_ASE   150  1           D   23.1.1.3        GigabitEthernet0/0/1

7.R4查看ISIS路由表

[R4]display ip routing-table protocol isis 
        3.3.3.3/32  ISIS-L2 15   74          D   34.1.1.3        GigabitEthernet0/0/0
       23.0.0.0/8   ISIS-L2 15   74          D   34.1.1.3        GigabitEthernet0/0/0
