华为策略路由配置实例

1、华为策略路由配置实例公司20.1 30.1/24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、配置流分类，匹配规则为上述ACL规则，使设备可以对报文进行区分

2、。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 o5、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 ,并加入VLAN100 和 VLAN200 oSwitch i
