Hi, we are using L3 HA in our production environment now. Router instances
communicate to each other by VRRP protocol. In my opinion, although VRRP is
a control plane thing, but the real VRRP traffic is using data plane nic so
that router namespaces can not talk to each other sometimes when the  data
plan is busy. If we were used etcd (or other), does every router instance
register one "id" in etcd ?
