OSPF配置ospf_cfg

基于华为交换机S3700-EI
OSPF典型配置什么是OSPFhttps://info.support.huawei.com/info-finder/encyclopedia/zh/OSPF.html

每个OSPF进程的Router ID要保证在OSPF网络中唯一，否则会导致邻居不能正常建立、路由信息不正确的问题。建议在OSPF设备上单独为每个OSPF进程配置全网唯一的Router ID；
OSPF协议将自治系统划分成不同的区域（Area），其中区域号（Area ID）是0的称为骨干区域。OSPF要求所有非骨干区域必须与骨干区域保持连通，并且骨干区域的设备之间也要保持连通；

SwitchA_Vlan

<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan batch 10 20
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] port link-type trunk
[SwitchA-GigabitEthernet1/0/1] port trunk allow-pass vlan 10
[SwitchA-GigabitEthernet1/0/1] quit
[SwitchA] interface gigabitethernet 1/0/2
[SwitchA-GigabitEthernet1/0/2] port link-type trunk
[SwitchA-GigabitEthernet1/0/2] port trunk allow-pass vlan 20
[SwitchA-GigabitEthernet1/0/2] quit

SwitchA_Vlanif

[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ip address 192.168.0.1 24
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] ip address 192.168.1.1 24
[SwitchA-Vlanif20] quit

SwitchA_OSPF

[SwitchA] ospf 1 router-id 10.1.1.1   //创建进程号为1，Router ID为10.1.1.1的OSPF进程
[SwitchA-ospf-1] area 0   //创建area 0区域并进入area 0视图
[SwitchA-ospf-1-area-0.0.0.0] network 192.168.0.0 0.0.0.255   //配置area 0所包含的网段
[SwitchA-ospf-1-area-0.0.0.0] quit
[SwitchA-ospf-1] area 1   //创建area 1区域并进入area 1视图
[SwitchA-ospf-1-area-0.0.0.1] network 192.168.1.0 0.0.0.255   //配置area 1所包含的网段
[SwitchA-ospf-1-area-0.0.0.1] return

SwitchB_OSPF_withoutIFcfg 省略接口及初始配置，参考SwitchA就行

[SwitchB] ospf 1 router-id 10.2.2.2
[SwitchB-ospf-1] area 0
[SwitchB-ospf-1-area-0.0.0.0] network 192.168.0.0 0.0.0.255
[SwitchB-ospf-1-area-0.0.0.0] return

SwitchC_OSPF_withoutIFcfg

[SwitchC] ospf 1 router-id 10.3.3.3
[SwitchC-ospf-1] area 1
[SwitchC-ospf-1-area-0.0.0.1] network 192.168.1.0 0.0.0.255
[SwitchC-ospf-1-area-0.0.0.1] return
