          Use of Multicast across Inter-domain Peering Points

Abstract

   This document examines the use of Source-Specific Multicast (SSM)
   across inter-domain peering points for a specified set of deployment
   scenarios.  The objectives are to (1) describe the setup process for
   multicast-based delivery across administrative domains for these
   scenarios and (2) document supporting functionality to enable this
   process.
