VLANIF与OSPF跨越三层网络通信配置示例

1、VLANIF与OSPF跨越三层网络通信配置示例1、组网需求图1配置通过VLANIF接口跨越三层网络通信组网图SwitchA如上图1所示，SwitchA和SwitchB分别下挂VLAN10的二层网络，和SwitchB之间通过三层网络互通，三层网络采用OSPF协议。要求两个二层网络的PC实现二层隔离三层互通。2、配置思路2.1、配置接口所属的VLAN，允许VLAN通过当前接口2.2、配置VLANIF接口的IP地址，实现三层互通。2.3、配置OSPF基本功能，实现路由互通。3、操作步骤3.1、配置SwitchA# 仓U建VLAN10和VLAN30。<HUAWEI>system-viewH
