H3C交换机（S5500）策略路由配置笔记

拓扑图：

网络情况如下：

用户1网络：172.16.1.0/24
用户2网络： 192.168.1.0/24
至出口1网络：172.16.100.0/24
至出口2网络：192.168.100.0/24

实现功能：用户1通过互联网出口1，用户2通过互联网出口2。
功能实现：在三层交换台机上配置默认路由，将数据包丢向192.168.100.253，再利用策略路由，凡是用户2网络IP192.168.1.0/24的地址都丢向172.16.100.253。

配置步骤：

说明：这里接口的配置等操作就不在写了。

1、首先建立默认路由，将所有的数据包都丢往出口2的下一节点192.168.100.253

[H3C5500] ip route-static 0.0.0.0 0.0.0.0 192.168.100.253

2、配置流分类1，对象为172.16.1.0/24的数据

[H3C5500]acl number 3001

[H3C5500-acl-adv-3001] rule 0 permit ip source 172.16.1.0 0.0.0.255

[H3C5500] quit

[H3C5500] traffic classifier 1

[H3C5500-classifier-1] if-match acl 3001

[H3C5500-classifier-1] quit

3、配置刚才定义的流分类的行为，定义如果匹配就下一跳至出口1即172.16.100.253

[H3C5500] traffic behavior 1

[H3C5500-behavior-1] redirect next-hop 172.16.100.253

[H3C5500-behavior-1] quit

4、将刚才设置的应用至QOS策略中，定义policy 1

[H3C5500] qos policy 1

[H3C5500-qospolicy-1] classifier 1 behavior 1

[H3C5500-qospolicy-1] quit

5、在接口上应用定义的QOS策略policy 1

[H3C5500] interface GigabitEthernet 1/0/15

[H3C5500-GigabitEthernet1/0/15] qos apply policy 1 inbound

[H3C5500-GigabitEthernet1/0/15] quit

至此，配置已完成。
