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。

$ sudo ovs-vsctl show225f3eb5-6059-4063-99c3-8666915c9c55    Bridge br-int        fail_mode: secure        Port br-int            Interface br-int                type: internal        Port "qvoc4493802-43"            tag: 1            Interface "qvoc4493802-43"        Port patch-tun            Interface patch-tun                type: patch                options: {peer=patch-int}        Port "qvof47c62b0-db"            tag: 1            Interface "qvof47c62b0-db"    Bridge br-tun        fail_mode: secure        Port "vxlan-0a00644d"            Interface "vxlan-0a00644d"                type: vxlan                options: {df_default="true", in_key=flow, local_ip="10.0.100.88", out_key=flow, remote_ip="10.0.100.77"}        Port patch-int            Interface patch-int                type: patch                options: {peer=patch-tun}        Port br-tun            Interface br-tun                type: internal    ovs_version: "2.0.2"

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。

~$ brctl showbridge name     bridge id               STP enabled     interfacesqbrf47c62b0-db          8000.56a7904c418d       no              qvbf47c62b0-db                                                        tapf47c62b0-db
