基于 https://blog.csdn.net/song7999/article/details/80403527 实验
先删除两台主机的GRE端口
[root @ base〜]＃ovs-vsctl del-port br-in gre10
[[email protected] ~]# ovs-vsctl del-port br-in gre10
添加vxlan端口
[[email protected] ~]# ovs-vsctl add-port br-in vx10 -- set interface vx10 type=vxlan options:remote_ip=192.168.60.78
[[email protected] ~]# ovs-vsctl add-port br-in vx10 -- set interface vx10 type=vxlan options:remote_ip=192.168.60.88
测试ping
