VXLAN source-interface not working in VYOS 1.3

Hello ,

I am trying to make a VXLAN tunnel over the VYOS devices using VyOS 1.3-rolling-202006010117 image but am not succeeding in that as the following below error is coming.

[ interfaces vxlan vxlan0 ]
WARNING: RFC7348 recommends VXLAN tunnels preserve a 1500 byte MTU
VyOS had an issue completing a command.

We are sorry that you encountered a problem while using VyOS.

So is it problem in the VYOS code or somewhere else ?
Because I tried to look for solution online but no luck.

@Tripti16 Can you try the latest rolling?

Hello sir,

I tried it on https://downloads.vyos.io/rolling/current/amd64/vyos-rolling-latest.iso
It’s working now. The above issue is not coming.
Was there some fix done ? Because earlier it wasn’t working.
