OSPF基础配置示例

1. 配置步骤:

• 要在路由器上配置OSPF，必须首先进入系统视图,然后执行 ospf [ process-id |router-id router-id ]命令以使能OSPF进程,并进入OSPF 视图。
• 执行ospf命令时，如果不输入process-id（该参数表示OSPF进程编号）的值，则process-id默认取值为1。router-id是一个32比特的二进制数，也经常表示为点分十进制数。如果在执行ospf命令时不指定router-id，则路由器会根据某种规则自动生成一个值来作为router-id。

R1:

ospf router-id 11.1.1.1
area 0
network 12.0.0.0 0.255.255.255
network 13.0.0.0 0.255.255.255
quit
area 1
network 172.16.0.0 0.0.0.255
network 1.0.0.0 0.255.255.255
quit

interface GigabitEthernet 2/0/0
ip address 172.16.0.1 24
quit
interface GigabitEthernet 2/0/1
ip address 1.0.0.1 8
quit
interface GigabitEthernet 0/0/1
ip address 13.0.0.1 8
interface GigabitEthernet 0/0/0
ip address 12.0.0.1 8
quit

R2:

ospf router-id 22.2.2.2
area 0
network 12.0.0.0 0.255.255.255
network 23.0.0.0 0.255.255.255
quit
area 2
network 2.0.0.0 0.255.255.255
network 10.0.0.0 0.255.255.255
quit

interface GigabitEthernet 2/0/1
ip address 12.0.0.2 8
quit
interface GigabitEthernet 2/0/0
ip address 23.0.0.1 8
quit
interface GigabitEthernet 0/0/0
ip address 2.0.0.1 8
quit
interface GigabitEthernet 0/0/1
ip address 10.0.0.0 8
quit

R3:

ospf router-id 33.3.3.3
area 0
network 13.0.0.0 0.255.255.255
network 23.0.0.0 0.255.255.255
quit
area 3
network 192.168.0.0 0.0.0.255
network 3.0.0.0 0.255.255.255
quit

interface GigabitEthernet 2/0/0
ip address 192.168.0.1 24
quit
interface GigabitEthernet 2/0/1
ip address 3.0.0.1 8
quit
interface GigabitEthernet 0/0/1
ip address 13.0.0.2 8
quit
interface GigabitEthernet 0/0/0
ip address 23.0.0.2 8
quit

在完成上述配置后,我们可以通过以下命令来对配置进行验证。

• display ospf [ process-id ] peer 查看路由器的邻居信息。
• display ospf [ process-id ] routing 查看路由器的OSPF 路由表。
