Server2上的虚机访问Server3的虚机

11 故障测试

Server1上的虚机持续访问Server3的虚机，中间断开Server1和Leaf1的链路，然后再恢复，观察流量是否有中断。

11-1
11-2

观察到流量始终没有丢包。

Server1上的虚机持续访问Server3的虚机，中间重启Leaf，然后再恢复，观察流量是否有中断。

11-4

在Server1上抓包，可以看到ping包从ens1f1发出，从ens1f0回复

11-5
11-6

ens1f0对应Leaf1,ens1f1对应的是Leaf2，那我们重启Leaf2，收发包应该都切到Leaf1，到ens1f0

11-7

并且中间没有丢包

11-8
