1、华为策略路由配置实例华为策略路由配置实例1、组网需求20.1.20.1/24贷司 20.1.30JZ24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，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

2、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#在 Switch 上创建 VLAN100 和 VLAN200 。 system-viewHUAWEI sysname SwitchSwitch vian batch 100 200#配置 Switch 上接口 GE1/0/1、GE1/0/2 和 GE2/0/1 的接口类型为 Trunk ,
