华为策略路由配置实例

1、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    如上图1所示，公司用户通过Switch双归属到外部网络设备。其中，一条是低速链路，网关为10.1.20.1/24；另外一条是高速链路，网关为10.1.30.1/24。    公司希望上送外部网络的报文中，

2、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。4、配置流行为，使满足不同规则的报文分别被重定向到10.1.20.1/24和10.1.30.1/24。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#
