ospf 修改DR

                                                           OSPF修改DR

 

 

 

 

 

配置完ip 和ospf後，咱們用命令 show ip ospf neighbor /查看BR DBR

R1#show ip ospf neighbor

 

Neighbor ID     Pri   State           Dead Time   Address         Interface

2.2.2.2           1   FULL/BDR        00:00:36    192.168.1.2     Ethernet0/0

3.3.3.3           1   FULL/DR         00:00:30    192.168.1.3     Ethernet0/0

R1#

 

咱們看到r3是DR   如今咱們想把r1修改爲DR

 

在r1上

R1(config)#int e0/0

R1(config-if)#ip os

R1(config-if)#ip ospf p

R1(config-if)#ip ospf priority 5

R1(config-if)#end

 

而後再每一個路由器上

r1#claer ip ospf process

r2#claer ip ospf process

r3#claer ip ospf process

同時敲上面的命令，記住，三臺路由器必須同時敲上clear ip ospf process的命令
