This document recommends deprecation of the use of Any-Source Multicast (ASM) for interdomain multicast. It recommends the use of Source-Specific Multicast (SSM) for interdomain multicast applications, and that hosts and routers that are expected to handle such applications fully support SSM. The recommendations in this document do not preclude the continued use of ASM within a single organisation or domain, and are especially easy to adopt when already using the preferred ASM protocol options there (PIM-SM).
