1.1 问题

通过配置静态路由协议ospf实现全网互通，按照图-1拓扑图所示

图-1

1.2 步骤

实现此案例需要按照如下步骤进行。

步骤一：配置交换机

1）S3700交换机配置

[Huawei]vlan batch 2 3            //创建VLAN2、3

[Huawei]interface Ethernet0/0/2

[Huawei-Ethernet0/0/2]port default vlan 2

[Huawei]interface Ethernet0/0/3

[Huawei-Ethernet0/0/3]port default vlan 3

[Huawei]interface Ethernet0/0/22

[Huawei-Ethernet0/0/22]port link-type trunk

[Huawei-Ethernet0/0/22]port trunk allow-pass vlan all

2）S5700交换机配置

[Huawei]vlan batch 2 3 4            //创建VLAN2、3、4

[Huawei]interface Vlanif 1

[Huawei-Vlanif4]ip address  192.168.1.254 24

[Huawei]interface Vlanif 2

[Huawei-Vlanif4]ip address  192.168.2.254 24

[Huawei]interface Vlanif 3

[Huawei-Vlanif4]ip address  192.168.3.254 24

[Huawei]interface Vlanif 4

[Huawei-Vlanif4]ip address  192.168.4.1 24

[Huawei]interface GigabitEthernet 0/0/1

[Huawei-GigabitEthernet0/0/1] port link-type trunk

[Huawei-GigabitEthernet0/0/1] port trunk allow-pass vlan all

[Huawei]interface GigabitEthernet 0/0/2

[Huawei-GigabitEthernet0/0/2] port link-type access

[Huawei-GigabitEthernet0/0/2] port default vlan 4

[Huawei]ospf 1

[Huawei-ospf-1]area 0

[Huawei-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255

[Huawei-ospf-1-area-0.0.0.0]network 192.168.2.0 0.0.0.255

[Huawei-ospf-1-area-0.0.0.0]network 192.168.3.0 0.0.0.255

[Huawei-ospf-1-area-0.0.0.0]network 192.168.4.0 0.0.0.255

[Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.4.2

步骤二：配置路由器

AR2220路由器配置如下

[Huawei]interface GigabitEthernet 0/0/0

[Huawei-GigabitEthernet0/0/0] ip address  192.168.4.2 24

[Huawei]interface GigabitEthernet 0/0/1

[Huawei-GigabitEthernet0/0/0] ip address  192.168.5.254 24

[Huawei]ospf 1

[Huawei-ospf-1]area 0

[Huawei-ospf-1-area-0.0.0.0]network 192.168.4.0 0.0.0.255
