8.7 ISIS协议重分布

1.R6、R7配置OSPF

[R6]ospf 1 router-id 6.6.6.6
[R6-ospf-1]area 0 
[R6-ospf-1-area-0.0.0.0]network 67.1.1.0 0.255.255.255
[R7]ospf 1 router-id 7.7.7.7
[R7-ospf-1]area 0 
[R7-ospf-1-area-0.0.0.0]network 7.7.7.7 0.0.0.0
[R7-ospf-1-area-0.0.0.0]network 67.1.1.0 0.255.255.255

2.R6在ISIS引入OSPF，R5查看路由信息

[R6]isis 1
[R6-isis-1]import-route ospf 1 level-1 
//R6是level-1区域路由器，引入时需要加level-1关键字，level-2不需要
<R5>display ip routing-table protocol isis
 1.1.1.1/32  ISIS-L2 15   40          D   45.1.1.4        GigabitEthernet0/0/0
        2.2.2.2/32  ISIS-L2 15   30          D   45.1.1.4        GigabitEthernet0/0/0
        3.3.3.3/32  ISIS-L2 15   20          D   45.1.1.4        GigabitEthernet0/0/0
        4.4.4.4/32  ISIS-L2 15   10          D   45.1.1.4        GigabitEthernet0/0/0
        6.6.6.6/32  ISIS-L1 15   10          D   56.1.1.6        GigabitEthernet0/0/1
        7.7.7.7/32  ISIS-L1 15   74          D   56.1.1.6        GigabitEthernet0/0/1
       12.0.0.0/8   ISIS-L2 15   40          D   45.1.1.4        GigabitEthernet0/0/0
       23.0.0.0/8   ISIS-L2 15   30          D   45.1.1.4        GigabitEthernet0/0/0
       34.0.0.0/8   ISIS-L2 15   20          D   45.1.1.4        GigabitEthernet0/0/0
       67.0.0.0/8   ISIS-L1 15   20          D   56.1.1.6        GigabitEthernet0/0/1

3.R6在OSPF引入ISIS，R7查看路由信息

[R6]ospf 1 
[R6-ospf-1]import-route isis 1
[R7]display ip routing-table protocol ospf 
 5.5.5.5/32  O_ASE   150  1           D   67.1.1.6        GigabitEthernet0/0/0
        6.6.6.6/32  O_ASE   150  1           D   67.1.1.6        GigabitEthernet0/0/0
       45.0.0.0/8   O_ASE   150  1           D   67.1.1.6        GigabitEthernet0/0/0
       56.0.0.0/8   O_ASE   150  1           D   67.1.1.6        GigabitEthernet0/0/0
