The IESG has approved the following document: - 'Deprecating ASM for Interdomain Multicast' (draft-ietf-mboned-deprecate-interdomain-asm-07.txt) as Best Current Practice This document is the product of the MBONE Deployment Working Group. The IESG contact persons are Warren Kumari and Ignas Bagdonas. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-mboned-deprecate-interdomain-asm/ Technical Summary 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 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. Working Group Summary There was some initial concern from a few individuals that ASM was still useful in intradomain deployments. The authors resolved these concerns by making it clear throughout the doc that this recommendation to deprecate ASM applies only to interdomain deployments and makes no recommendations for intradomain multicast deployments. Other than this, no other controversies with this document were noted. Document Quality Document is well written, defining a clear problem statement and supporting scenarios and examples for the core recommendations. Assumptions regarding the future-state of ASM protocols are appropriately highlighted, and the impact on the document recommendations are addressed.
