计算节点

主要包括两个网桥：集成网桥 br-int 和 隧道网桥 br-tun。

安全网桥可以通过 brctl show 命令看到，该网桥主要用于绑定控制组的 iptables 规则，跟转发无直接关系。

  1. ~$ brctl show
  2. bridge name     bridge id               STP enabled     interfaces
  3. qbrf47c62b0-db          8000.56a7904c418d       no              qvbf47c62b0-db
  4.                                                         tapf47c62b0-db
