华为路由器 OSPF单区域配置

拓扑图

一、R1 路由器

<Huawei> sys
[Huawei]sys R1
[R1]un in en
[R1]dhcp enable
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip addr 192.168.20.2 24

# 配置DHCP
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]ip addr 192.168.10.1 24
[R1-GigabitEthernet0/0/1]dhcp select int
[R1-GigabitEthernet0/0/1]quit

# 配置OSPF
[R1]ospf 1 router-id 1.1.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 192.168.10.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]network 192.168.20.0 0.0.0.255

二、R2 路由器

[Huawei]sys R2
[R2]un in en
[R2]int g0/0/1
[R2-GigabitEthernet0/0/1]ip addr 192.168.30.1 24
[R2-GigabitEthernet0/0/1]int g0/0/0
[R2-GigabitEthernet0/0/0]ip addr 192.168.20.1 24
[R2-GigabitEthernet0/0/0]quit

# 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 192.168.20.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]network 192.168.30.0 0.0.0.255

三、R3 路由器

[Huawei]sys R3
[R3]un in en
[R3]dhcp enable
[R3]int g0/0/0
[R3-GigabitEthernet0/0/0]ip addr 192.168.30.2 24
[R3-GigabitEthernet0/0/0]int g0/0/1
[R3-GigabitEthernet0/0/1]ip addr 192.168.40.1 24
[R3-GigabitEthernet0/0/1]dhcp select int
[R3-GigabitEthernet0/0/1]quit

# 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 192.168.30.0 0.0.0.255
[R3-ospf-1-area-0.0.0.0]network 192.168.40.0 0.0.0.255

四、验证

1、R1 查看邻居表

# 只有 2.2.2.2 一个邻居ID
[R1]dis ospf peer

    OSPF Process 1 with Router ID 1.1.1.1
       Neighbors 

 Area 0.0.0.0 interface 192.168.20.2(GigabitEthernet0/0/0)'s neighbors
 Router ID: 2.2.2.2          Address: 192.168.20.1    
   State: Full  Mode:Nbr is  Master  Priority: 1
   DR: 192.168.20.1  BDR: 192.168.20.2  MTU: 0    
   Dead timer due in 37  sec 
   Retrans timer interval: 5 
   Neighbor is up for 00:13:35     
   Authentication Sequence: [ 0 ]
