MPLS Virtual Private Networks (VPNs) in RFC-2547bis
defines a mechanism by which service providers can use
their IP backbones to provide VPN services to customers.
A VPN is a set of sites which share common routing
information and whose connectivity is controlled by
a collection of policies. RFC-2547bis VPNs are also
known as BGP-MPLS VPNs because the Border Gateway Protocol
(BGP) is used to distribute VPN routing information
across the provider's backbone, and MPLS is used to
establish virtual circuits to forward VPN traffic across
the backbone to remote VPN sites.
