The IESG has received a request from the Protocols for IP Multicast WG (pim) to consider the following document: - 'Zeroconf Multicast Address Allocation Problem Statement and Requirements' <draft-ietf-pim-zeroconf-mcast-addr-alloc-ps-07.txt> as Informational RFC
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2025-10-17. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document defines the problem space and associated requirements for automatically assigning multicast addresses in zero-configuration ("zeroconf") networking environments. It addresses key challenges, such as address collisions, hardware limitations, multicast snooping inefficiencies, and the need to avoid manual configuration. Based on these challenges, it derives requirements for a lightweight, decentralized protocol capable of dynamically allocating unique multicast group addresses without central coordination. The document presents explicit requirements covering discovery, allocation, conflict detection and resolution, and lease management. It also evaluates considerations specific to IPv6 and IPv4 multicast address ranges, and identifies approaches that are unsuited for zeroconf deployment. This foundation serves as a reference for developing future multicast address allocation protocols that operate autonomously within local networks. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-pim-zeroconf-mcast-addr-alloc-ps/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
