Variable refrigerant flow. Variable refrigerant flow (VRF), also known as variable refrigerant volume (VRV), is an HVAC technology invented in Japan by Daikin company in 1982. Like ductless minisplits VRFs use refrigerant as the cooling and heating medium.
When you create a vrf, you tell it what routes to import/export. Then you assign that vrf to an interface. Once the vrf is attached to an interface, the switch/router creates a separate routing table to hold those routes. To see those, you'd type sho ip route vrf MGNT-VRF.
