VXLAN has state A/D after configuration
Closed, ResolvedPublicBUG

Description

The issue described in the forum topic https://forum.vyos.io/t/vyos-1-3-rolling-202008200357-vxlan-not-working/5823
In rolling releases, VXLAN always has state A/D
Reproducing steps:

set interfaces vxlan vxlan1 address '172.16.0.2/24'
set interfaces vxlan vxlan1 mtu '1500'
set interfaces vxlan vxlan1 remote '192.168.255.15'
set interfaces vxlan vxlan1 vni '1'
vyos@vyos#  run show interfaces vxlan 
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface        IP Address                        S/L  Description
---------        ----------                        ---  -----------
vxlan1           172.16.0.2/24                     A/D

If change interface status manually, it works.

vyos@vyos#  run show interfaces vxlan 
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface        IP Address                        S/L  Description

vxlan1           172.16.0.2/24                     u/u
