华为策略路由配置实例

1、共享知识分享快乐华为策略路由配置实例1、组网需求20.1.20.1724公司20,1,30.他4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

2、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 。<HUAWEI> system-viewHUAWEI sysname SwitchSwitch vlan 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
