配置需求及实现的效果

交换机SW1上配置一条静态路由，使终端访问114.114.114.114的时候通过R2，其中192.168.2.0这个网段，访问114.114.114.114 的时候匹配策略路由从R3去访问。

3 配置步骤

一．交换机和路由器上ip地址基本配置

#在SW1上进图系统视图

<H3C>system-view

System View: return to User View with Ctrl+Z.

#创建vlan 1-4

[H3C]vlan 1 to 4

#配置vlan 1-vlan 4虚接口IP地址

[H3C]interface Vlan-interface 1

[H3C-Vlan-interface1] ip address 192.168.1.1 255.255.255.0

[H3C-Vlan-interface1]quit

[H3C]interface Vlan-interface 2

[H3C-Vlan-interface2] ip address 192.168.2.1 255.255.255.0

#配置到114.114.114.0网段的静态路由

#配置到192.168.1.0网段的静态路由

[H3C]ip route-static 192.168.1.0 24 30.30.30.2

#配置到114.114.114.0网段的静态路由

二．交换机策略路由配置

<H3C>system-view

System View: return to User View with Ctrl+Z.

#定义访问控制列表3000，用来匹配内网源地址为192.168.2.0/24网段的数据流

[H3C]acl advanced 3000

[H3C-acl-ipv4-adv-3000]rule permit ip source 192.168.2.0 0.0.0.255

[H3C-acl-ipv4-adv-3000]quit

# 定义访问控制列表3001，用来匹配内网192.168.2.0/24网段去访问内网192.168.1.0/24网段的数据流。

[H3C]acl advanced 3001

[H3C-acl-adv-3001]rule permit ip source 192.168.2.0 0.0.0.255 destination 192.168.1.0 0.0.0.255

[H3C-acl-adv-3001]quit

# 创建策略路由，名称为aaa，节点为10，匹配acl 3001的数据流，不设置apply动作（如果不设置动作，则匹配到的数据转发时根据路由表来进行转，且不再匹配下一节点，配置这个节点的作用是实现内网不同网段之间互访的流量不匹配策略路由，达到可以互访的目的。备注：默认情况下，网关在路由器上的不同网段是可以互相访问的）。

[H3C]policy-based-route aaa permit node 10

[H3C-pbr-aaa-10]if-match acl 3001

[H3C-pbr-aaa-10]quit

#创建策略路由aaa的节点20，匹配acl 3000的数据流，设置apply动作，指定数据的下一跳为20.20.20.2。

[H3C]policy-based-route aaa permit node 20

[H3C-pbr-aaa-20]if-match acl 3000

[H3C-pbr-aaa-20]apply next-hop 20.20.20.2

[H3C-pbr-aaa-20]quit

#在内网VLAN虚接口（网关）上应用策略路由

[H3C]interface vlan 2

[H3C-Vlan-interface2]ip policy-based-route aaa

[H3C-Vlan-interface2]quit

[H3C]save force

4 验证配置

# 交换机上没有配置策略路由的时候，在两台终端上tracert路径的结果如下：

192.168.1.2：

192.168.2.2：

# 配置了策略路由以后

192.168.1.2：

192.168.2.2：
