Step
by Step Into MPLS – VRF LITE
Although VRF (virtual routing and
forwarding) is not actually part of the MPLS you can think of the VRF as a
helper for the MPLS in achieving the MPLS VPN infrastructure, now as I would
like to make that a very simple to understand guide , I will address here only
the VRF part without any MPLS, also known as VRF Lite.
