不需要什么命令去开户。
它的三层功能实现，就是单臂路由的形式。不需要写入路由条目，跟路由器的直连路由一个道理。
华三路由器的这几条命令是什么意思啊？
nqa entry imclinktopologypleaseignore ping
type icmp-echo
destination ip 10.45.17.38
frequency 270000
nqa是一个检测技术
这组命令就是
使用icmp协议 也就是ping 去探测10.45.17.38这个ip地址是否能通
华为交换机S5720配置nqa+静态路由切换
一、实验拓扑
二、SW2配置
nqa test-instance helipay icmp
test-type icmp
destination-address ipv4 2.2.2.10 //探测的目标地址
frequency 10 //检测周期10秒
interval seconds 3 //周期内发的三次包时间间隔,该数值乘于3，不能超过周期设置值
start now
//静态路由关联内容
ip route-static 0.0.0.0 0.0.0.0 Vlanif100 1.1.1.2 track nqa helipay icmp //必须带出接口
ip route-static 0.0.0.0 0.0.0.0 1.1.1.3 preference 100
三、状态查看
dis nqa results //产看探测结果
“Lost packet ratio: 0 %”，这说明链路状态完好。
“Lost packet ratio: 100%”，这说明链路状态发生故障
dis nqa history //产看探测包的记录情况
四、测试情况
关闭SW6上的接口，路由表会进行切换，如下：
五、探测回复后
若是探测IP回复了，nqa是不支持抢占的，需要先关闭nqa探测。
nqa test-instance helipay icmp
undo start //结束探测，路由才会基于优先级高低重新更新
start now //然后重新再启用探测
