Summary

The PIM working group meeting in Yokohama covered a wide range of topics related to multicast routing and address allocation. Key discussions included updates on existing drafts, presentations on new protocols like PIM-FRR based on TI-LFA and GAP, and considerations for scaling multicast deployments. The group also discussed the need to update older RFCs like 1112.

Key Discussion Points

PIM Election Drafts: Progress needed on existing PIM election drafts.
RFC Status: Updates on several RFCs approved for publication (register packing, a-start packing, proxy YANG).
BIZ Documents: Discussion of moving IGMP and MLD to full Internet Standard via BIZ documents.
PIM Light: Presentation on PIM Light, focusing on point-to-point deployments, TCP interaction, and the need for clarity regarding multi-access considerations.
PIM-FRR based on TI-LFA: Presentation on a new mechanism for PIM-FRR based on TI-LFA and requests for working group last call
Backup DR: Presentation on backup DR election and sticky DR behavior with a discussion of interactions with another related draft.
GAP (Group Allocation Protocol): Presentation on a new decentralized multicast group allocation protocol with discussion of collision resolution, security, and API design.
Zero Config Multicast Address Allocation: Presentation on a zero-configuration approach to multicast address allocation for layer 2 networks using mDNS.
MLD Proxy with Multi-Streaming Interfaces: Presentation on supporting multiple interfaces in MLD proxies with different access technologies.
RFC 1112 Update: Discussion on updating RFC 1112 to remove IGMPv1, apply to IPv6, and incorporate ASM terminology.
Scaling Multi-Cast using Tunnels: Presentation around how to scale the different dimensions that exist when considering multi-cast networks

Decisions and Action Items

P2P Policy PING: Resend a new email requesting early allocation for P2P Policy PING to the ADs and Mp chairs, copying the original request.
PIM Light: Update the PIM Light draft based on feedback received, clarifying its applicability to point-to-point deployments and addressing multi-access concerns.
PIM-FRR based on TI-LFA: Take the PIM-FRR draft to the mailing list to determine if there is any outstanding feedback before beginning working group last call.
Backup DR: Analyze the interplay between the sticky DR approach and another draft, and discuss which one works best.
GAP (Group Allocation Protocol): Need to better explain to other members how to resolve collision
RFC 1112 Update: Tore to discuss updates with Jim (the AD) regarding process.

Next Steps

Discussions on various topics will continue on the mailing list.
Adoption calls for several drafts will be initiated on the mailing list.
Further testing and development of GAP will be conducted.
Further development and analysis for the Backup DR case will be done
