实验过程

两台机器都要执行

1.创建vxlan

ip link add vxlan0 type vxlan id 42 dstport 4789 local 172.17.0.12 group 233.1.1.1 dev eth0

[root@172-17-0-12 ~]# ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
