OSPF与静态路由的重分布配置

OSPF与静态路由的重分布配置

OSPF与静态路由分布配置

如上例图所示：“RIP与OSPF路由重分布例子”

switchA(config)#router ospf

switchA(config-router)#network 192.168.10.0 0.0.0.255 area 0

switchA(config-router)#network 192.168.20.0 0.0.0.255 area 0

switchA(config-router)#network 192.168.1.0 0.0.0.255 area 0

switchA(config-router)#exit

switchA(config)#end

router(config)#router ospf

router(config-router)#network 192.168.1.0 0.0.0.255 area 0

router(config-router)#network 192.168.2.0 0.0.0.255 area 0

router(config-router)#exit

router(config)#ip route 192.168.30.0 255.255.255.0 192.168.2.1

router(config)#ip route 192.168.40.0 255.255.255.0 192.168.2.1

router(config)#end

switchB(config)#ip route 192.168.10.0 255.255.255.0 192.168.2.2

switchB(config)#ip route 192.168.20.0 255.255.255.0 192.168.2.2

switchB(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.1

switchB(config)#end

在互连路由器上进行重分布配置，使其两个不同路由协议的网络进行互通

Router(config)#router ospf

Router(config-router)#redistribute static subnets//将OSPF重分布到静态路由

Router(config-router)#exit

Router(config)#end

此例我只是做了把OSPF重分布到静态路由，是因为静态路由本身就是一个明确的邻接路由，因为我们在switchB上已经明确指定静态路由了，所以就没有做相关的重分布配

置，话说过来，网络设备也没有提供相就的静态路由重分布的方法。

配置好后：三台设备的路由表情况如下：

Router:

Router#show ip route

Codes: C - connected, S - static, R - RIP B - BGP

O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

* - candidate default

Gateway of last resort is no set

C 192.168.1.2/32 is local host.

C 192.168.2.0/24 is directly connected, FastEthernet 0/1

C 192.168.2.2/32 is local host.

O 192.168.10.0/24 [110/2] via 192.168.1.2, 1d,22:44:08, FastEthernet 0/0

C 192.168.10.1/32 is local host.

C 192.168.20.0/24 is directly connected, VLAN 20

C 192.168.20.1/32 is local host.

switchB:

switchB#show ip route

Codes: C - connected, S - static, R - RIP B - BGP

O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

Gateway of last resort is no set

C 192.168.2.0/24 is directly connected, FastEthernet 0/1

C 192.168.2.1/32 is local host.

S 192.168.10.0/24 [1/0] via 192.168.2.2

S 192.168.20.0/24 [1/0] via 192.168.2.2

S 192.168.1.0/24 [1/0] via 192.168.2.2

C 192.168.40.0/24 is directly connected, VLAN 20

C 192.168.40.1/32 is local host.

根据上述的路由表的分析我们得知OSPF与static的路由重分布成功。
