华为策略路由配置实例1、组网需求?????????????????图1?策略路由组网示例图????公司希望上送外部网络的报文中，IP优先级为4、5、6、7的报文通过高速链路传输，而IP优先级为0、1、2、3的报文则通过低速链路传输。

2、配置思路1、创建VLAN并配置各接口，实现公司和外部网络设备互连。

2、配置ACL规则，分别匹配IP优先级4、5、6、7，以及IP优先级0、1、2、3。

3、配置流分类，匹配规则为上述ACL规则，使设备可以对报文进行区分。

5、配置流策略，绑定上述流分类和流行为，并应用到接口GE2/0/1的入方向上，实现策略路由。

3、操作步骤3.1、创建VLAN并配置各接口#?在Switch上创建VLAN100和VLAN200。
