VLANIF與OSPF跨越三層網(wǎng)絡(luò)通信配置示例

1、VLANIF與OSPF跨越三層網(wǎng)絡(luò)通信配置示例1、組網(wǎng)需求                  圖1 配置通過VLANIF接口跨越三層網(wǎng)絡(luò)通信組網(wǎng)圖如上圖1所示，SwitchA和SwitchB分別下掛VLAN10的二層網(wǎng)絡(luò)，SwitchA和SwitchB之間通過三層網(wǎng)絡(luò)互通，三層網(wǎng)絡(luò)采用OSPF協(xié)議。要求兩個二層網(wǎng)絡(luò)的PC實現(xiàn)二層隔離三層互通。  2、配置思路2.1、配置接口所屬的VLAN，允許VLAN通過當(dāng)前接口。2.2、配置VLANIF接口的IP地址，實現(xiàn)三層互通

2、。2.3、配置OSPF基本功能，實現(xiàn)路由互通。  3、操作步驟3.1、配置SwitchA# 創(chuàng)建VLAN10和VLAN30。<HUAWEI> system-viewHUAWEI sysname SwitchASwitchA vlan batch 10 30 # 配置接口GE1/0/1加入VLAN 10，GE1/0/2加入VLAN 30。SwitchA interface gigabitethernet 1/0/1SwitchA-GigabitEthernet1/0/1 port link-type trunkSwitchA-Giga
