DSTPORT=4789
LOCAL_ADDR="192.168.1.1"
PHYS_DEV="eth0"
OPTIONS="nolearning"
BRIDGE="br1000"

Sample configuration for a vxlan interface that lets the kernel determine the output interface and uses static flooding to distribute BUM packets.:

DEVICE=vxlan1000
BOOTPROTO=none
ONBOOT=yes
TTL=255
VNI=1000
DSTPORT=4789
LOCAL_ADDR="192.168.1.1"
REMOTE_VTEPS="192.168.1.2 192.168.1.3 192.168.1.4"
BRIDGE="br1000"
