It would be really cool if VyOS could show the interface description (when set) on autocompleting interface names. That would help avoiding stupid errors.
$ show interfaces tun0 192.168.10.121/31 u/u VRF VoIP Tunnel to Customer xx tun1 172.16.255.1/31 u/u VRF VoIP Tunnel to Customer xy
Currently (both in configure and in show mode)
vyos@vyos# set vrf name VoIP protocols static route 172.16.136.72/29 interface <TAB> Possible completions: > <text> Gateway interface name > tun0 > tun1
Desired
vyos@vyos# set vrf name VoIP protocols static route 172.16.136.72/29 interface <TAB> Possible completions: > <text> Gateway interface name > tun0 VRF VoIP Tunnel to Customer xx > tun1 VRF VoIP Tunnel to Customer xy
