1、vtep-ctl add-ps br0
2、vtep-ctl set Physical_Switch br0 tunnel_ips=192.168.16.81，…………
vtep只能绑定一个bridge
可以添加多个logic switch
3、 vtep-ctl add-ls ls0
4、 vtep-ctl bind-ls br0 p0 100 ls0
5、 vtep-ctl set Logical_Switch ls0 tunnel_key=33
6、 vtep-ctl add-ucast-remote ls0 d2:40:3e:24:38:f6 192.168.16.83
添加一个单播地址,每添加一个形成一个Port "vx"
7、 vxlan本地ip: enahisic2i2 192.168.16.82/24,网卡enahisic2i2不需要加入ovs
