The purpose of this document is to define a BGP-based auto-discovery
mechanism for Layer-1 VPNs (L1VPNs).  The
auto-discovery mechanism for L1VPNs allows the provider network
devices to dynamically discover the set of Provider Edges (PEs) having
ports attached to Customer Edge (CE) members of the same VPN.  That
information is necessary for completing the signaling phase of L1VPN
connections.  One main objective of a L1VPN auto-discovery mechanism is
to support the "single-end provisioning" model, where addition of a
new port to a given L1VPN would involve configuration changes only on
the PE that has this port and on the CE that is connected to the PE
via this port.  [STANDARDS TRACK]
