Technical Summary
 
 This memo describes security threats for the larger (intra-domain, or
 inter-domain) multicast routing infrastructures.  Only Protocol
 Independent Multicast - Sparse Mode (PIM-SM) is analyzed, in its
 three main operational modes: the traditional Any Source Multicast
 (ASM) model, Source-Specific Multicast (SSM) model, and the ASM model
 enhanced by the Embedded-RP group-to-RP mapping mechanism.  This memo
 also describes enhancements to the protocol operations to mitigate
 the identified threats.
