Sometimes one might wan't to switch it's vbash to a different VRF. This can be done by: sudo ip vrf exec mgmt su - $(whoami)
vyos@vyos:~$ ip vrf identify vyos@vyos:~$ sudo ip vrf exec mgmt su - $(whoami) vyos@vyos:~$ ip vrf identify mgmt
But it might also be nice to see this reflected on the prompt for a better user experience, something like: vyos@vyos:mgmt#
One can also use the new CLI command to move to a different VRF:
vyos@vyos:~$ force vrf mgmt vyos@vyos:mgmt:~$ configure
