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
