SR66SR66-X系列路由器使用HQOS达到主备链路流量切换功能典型配置

FTP Server侧路由器关键配置

//基本路由及IP地址配置省略

// 匹配业务流

acl number 3001

rule 0 permit ip source 192.168.1.2 0 destination 172.16.1.2 0

//匹配溢出流量   network= 7   

acl number 3002

rule 0 permit ip precedence network    

 //IP优先级为7即溢出流量的报文下一跳为20.0.0.1

policy-based-route backup permit node 10

if-match acl 3002
