Deprecating Any-Source Multicast (ASM) for Interdomain Multicast
Mikael Abrahamsson, Tim Chown, L. Giuliano, Toerless Eckert · 2020
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 recommends that hosts and routers in these deployments 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 in existing intradomain ASM/PIM-SM deployments.
