When creating a VXLAN interface, specifying a group also requires setting a link interface but this is not checked for when commiting and gives the following error instead
[ interfaces vxlan vxlan0 ]
vxlan: 'group' requires 'dev' to be specified
Cannot find device "vxlan0"
unlike, for example, setting a BGP peer without a remote AS number which shows a error and quits the commit
[ protocols bgp 1 neighbor 192.168.0.1 ]must set remote-as or peer-group with remote-as defined
