A new Request for Comments is now available in online RFC libraries. RFC 9466 Title: PIM Assert Message Packing Author: Y. Liu, Ed., T. Eckert, Ed., M. McBride, Z. Zhang Status: Standards Track Stream: IETF Date: October 2023 Mailbox: liuyisong@chinamobile.com, tte@cs.fau.de, michael.mcbride@futurewei.com, zhang.zheng@zte.com.cn Pages: 20 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-pim-assert-packing-12.txt URL: https://www.rfc-editor.org/info/rfc9466 DOI: 10.17487/RFC9466 When PIM Sparse Mode (PIM-SM), including PIM Source-Specific Multicast (PIM-SSM), is used in shared LAN networks, there is often more than one upstream router. This can lead to duplicate IP multicast packets being forwarded by these PIM routers. PIM Assert messages are used to elect a single forwarder for each IP multicast traffic flow between these routers. This document defines a mechanism to send and receive information for multiple IP multicast flows in a single PackedAssert message. This optimization reduces the total number of PIM packets on the LAN and can therefore speed up the election of the single forwarder, reducing the number of duplicate IP multicast packets incurred. This document is a product of the Protocols for IP Multicast Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
