1、在总部三层交换机建立vlan80，配置连接的端口。命令如下：[Huawei]vlan 80[Huawei-vlan80]quit[Huawei]interface g0/0/8[Huawei-GigabitEthernet0/0/8]port link-type access[Huawei-GigabitEthernet0/0/8]port default vlan 80[Huawei-GigabitEthernet0/0/8]quit[Huawei]
2、配置VLANif的接口。[Huawei]interface vlanif80[Huawei-Vlanif80][Huawei-Vlanif80]ip address 192.168.80.254 24[Huawei-Vlanif80]dis this[Huawei-Vlanif80]quit[Huawei]
3、配置回程路由[Huawei]ip route-static 192.168.10.0. 255.255.255.0 192.168.80.1
