现象：
两个vs中配置了同一个svc地址，导致其中的一个vs路由配置不生效，看到istiod服务的报错duplicate domain from service
解决：
istiod服务报错日志

配合istioctl的其它子命令进行验证
# 查看侦听器配置
istioctl proxy-config listeners xxx-pod.xx-ns |grep "xx"

10.99.46.36 80 ALL Cluster: outbound|80||mp-x.ns.svc.cluster.local
# 查看集群cluster配置
istioctl proxy-config clusters xx-pod.ns |grep "xx"
xx.ns.svc.cluster.local 80 - outbound EDS

# 路由配置
istioctl proxy-config routes xx-pod.ns |grep -E "tts"
deploymentxx.ns.svc.cluster.local:80 deploymentxx.ns.svc.cluster.local:80 * /* svc1-name-virtualservice.ns
