Abstract

   This memo presents an approach for building core Virtual Private
   Network (VPN) services in a service provider's MPLS backbone.  This
   approach uses Multiprotocol Label Switching (MPLS) running in the
   backbone to provide premium services in addition to best effort
   services. The central vision is for the service provider to provide a
   virtual router service to their customers. The keystones of this
   architecture are ease of configuration, user security, network
   security, dynamic neighbor discovery, scaling and the use of existing
   routing protocols as they exist today without any modifications.
