H3C NQA+track 实现 双链路主备切换

1.静态路由配置
ip route-static 0.0.0.0 0 1.1.1.2     track 1  

主路由关联track 1

ip route-static 0.0.0.0 0 2.2.2.2 preference 100

备路由优先级修改为100

2.NQA配置
1).创建检测组
nqa entry admin test1
type icmp-echo
destination ip 8.8.8.8
next-hop ip 1.1.1.2
创建test1，类型ICMP，探测目标地址8.8.8.8，下一跳 1.1.1.2
probe count 10
probe timeout 500    
frequency 3000
reaction 1 checked-element probe-fail threshold-type consecutive 3 action-type                         trigger-only
连续检测失败3次触发
quit

        2).启动检测

nqa schedule admin test1 start-time now lifetime forever

3.NQA关联track1
track 1 nqa entry admin test1 reaction 1
