华为路由器配置策略路由示例（策略路由、PBR）

组网需求
企业用户希望根据用户实际需求制定策略进行路由选择，使不同的数据流通过不同的链路进行发送，增强路由选择的灵活性和可控性，提高链路的利用效率和降低企业成本。为实现上述需求，可以使用策略路由。
如图所示，RouterA、RouterB和RouterC使用OSPF保证全网路由可达，并且在RouterA上察看路由表可以发现到10.0.0.0的下一跳为RouterC的GE1/0/0接口地址。

在RouterA的上应用策略路由，使从10.0.2.0/24到10.0.0.0/24的流量重定向到RouterB上。

操作步骤
配置RouterA
    #                                                                               
    acl number 3001    //定义ACL匹配目的源地址是10.0.2.0/24，目的地址是10.0.0.0/24    
     rule 5 permit ip source 10.0.2.0 0.0.0.255 destination 10.0.0.0 0.0.0.255     
    #                                                                               
    traffic classifier rdt operator or  //定义需要重定向的数据流分类
     if-match acl 3001                                                              
    #                                                                               
    traffic behavior rdt  //定义流行为为重定向到RouterB的GE1/0/0的接口地址
     redirect ip-nexthop 10.181.10.2                                                
    #                                                                               
    traffic policy rdt  //绑定流策略
     classifier rdt behavior rdt                                                    
    #                                                                               
    interface GigabitEthernet 1/0/0                                                  
     ip address 10.181.20.1 255.255.255.0    
    #                                                                               
    interface GigabitEthernet 2/0/0                                                         
     ip address 10.181.10.1 255.255.255.0
    #                                                                               
    interface GigabitEthernet 3/0/0                                                         
     ip address 10.0.2.1 255.255.255.0
     traffic-policy rdt inbound  //从10.0.2.0/24到10.0.0.0/24的流量重定向到RouterB上
    #                                                                               
    ospf 1     //配置OSPF路由协议                                                                          
     area 0.0.0.0                                                                   
      network 10.0.2.0 0.0.0.255                                                 
      network 10.181.20.0 0.0.0.255                                                 
      network 10.181.10.0 0.0.0.255   
    #                                                                               
    return

配置RouterB
    #                                                                               
    interface GigabitEthernet 1/0/0                                                         
     ip address 10.181.10.2 255.255.255.0   
    #                                                                               
    interface GigabitEthernet 2/0/0                                                         
     ip address 10.184.10.1 255.255.255.0   
    #                                                                               
    ospf 1    //配置OSPF路由协议                                                                        
     area 0.0.0.0                                                                   
      network 10.181.10.0 0.0.0.255                                                 
      network 10.184.10.0 0.0.0.255  
    #
    return

配置RouterC
    #                                                                               
    interface GigabitEthernet 1/0/0                                                  
     ip address 10.181.20.2 255.255.255.0  
    #                                                                               
    interface GigabitEthernet 2/0/0                                                         
     ip address 10.184.10.2 255.255.255.0   
    #                                                                               
    ospf 1        //配置OSPF路由协议                                                                  
     area 0.0.0.0                                                                   
      network 10.184.10.0 0.0.0.255                                                 
      network 10.181.20.0 0.0.0.255     
      network 10.0.0.0 0.0.0.255                                                 
    #
    return

验证配置结果
    # 在10.0.2.0/24网段的主机上执行tracert命令，检测从10.0.2.0/24到10.0.0.0/24的路径。发现从10.0.2.0/24到10.0.0.0/24的流量重定向到RouterB上。
