企业常用OSPF组网配置示例

 

1、组网需求

 

         图1、企业常用ospf组网示例图（点击图片放大查看高清示例图）

如上图1要求各分公司与总公司之间用ospf连接。

由于特殊原因，新成立的分公司3无法与总公司直连，所以通过分公司2做vlink peer来实现与总公司的ospf连接。

 

2、配置思路

创建vlan把不同用户加入不同的vlan，实现二层隔离

总公司与分公司直连的连接采用trunk端口来实现通信

 

3、具体配置

具体配置以及配置命令的释义请参见ospf配置教程（http://www.023wg.com/tag/ospf）和vlan配置教程（http://www.023wg.com/tag/vlan）
