一、 組網需求：
當防火墻有雙公網出口時，根據用戶的源地址或者需要訪問目的地址來選擇防火墻的轉發出口，從而實現路由選擇。
二、 配置步驟：
適用版本：Secpath1800F 所有VRP版本
acl number 2001rule 0 permit source 10.1.0.0 0.0.255.255
acl number 3001 // 定義與策略路由相關的
aclrule 0 deny ip source 10.1.1.0 0.0.0.255 // 10.1.1.0 網段不作策略路由
rule 5 permit ip source 10.1.2.0 0.0.0.255 // 源地址為10.1.2.0 的網段做策略路由
rule 10 permit ip destination 202.96.199.0 0.0.0.255// 目的地址為202.96.199.0 的網段做策略路由

三、 配置關鍵點：
配置策略路由時，主要要打開做相應的策略路由的域之間的規則。特別要注意的是，對于Version 3.30 Release 0336 以前的版本，存在策略路由根據默認路由域之間的規則來決定是否允許轉發的問題。
