Abstract

   This document describes procedures for building inter-area point-to-
   multipoint (P2MP) segmented service LSPs by partitioning such LSPs
   into intra-area segments and using BGP as the inter-area routing and
   label distribution protocol. Within each IGP area the intra-area
   segments are either carried over intra-area P2MP LSPs, using P2MP LSP
   hierarchy, or instantiated using ingress replication.  The intra-area
   P2MP LSPs may be signaled using P2MP RSVP-TE or P2MP mLDP. If ingress
   replication is used within an IGP area, then MP2P LDP LSPs or P2P
   RSVP-TE LSPs may be used in the IGP area. The applications/services
   that use such inter-area service LSPs may be BGP MVPN, VPLS
   multicast, or global table multicast over MPLS.
