Virtual Routing and Forwarding-VRF es una técnica de virtualizar las
tablas de enrutamiento de un router con el objetivo de que un Proveedor
de Servicios de Internet-ISP separe sus clientes.
Cisco hace suyo VRF
Juniper lo denomina
“routing instances”
Linux denomina
“network namespaces”
Huawei denomina “VPN Routing”

Los VRF emplean esencialmente el mismo concepto que VLAN y trunking, pero en la capa tres.

In Cisco terminology, deployment of VRFs without MPLS is
known as VRF lite,
