The IESG has approved the following document: - 'Protocol Independent Multicast (PIM) over Virtual Private LAN Service (VPLS)' (draft-ietf-pals-vpls-pim-snooping-06.txt) as Informational RFC This document is the product of the Pseudowire And LDP-enabled Services Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-pals-vpls-pim-snooping/ Technical Summary This document describes the procedures and recommendations for Virtual Private LAN Service (VPLS) Provider Edges (PEs) to facilitate replication of multicast traffic to only certain ports (behind which there are interested Protocol Independent Multicast (PIM) routers and/or Internet Group Management Protocol (IGMP) hosts) via Protocol Independent Multicast (PIM) snooping and proxying. Working Group Summary The primary thing to note about the WG process was the length of time it's taken to get this done. This is primarily due to two factors. The first is that it started in the L2VPN WG, and there was a five-year gap between draft-ietf-l2vpn-vpls-pim-snooping revisions -01 and -02. My nderstanding is that was due to the implementors both gaining experience with deployed code at that time, and not having the time to get back to the draft. Once the work restarted in L2VPN, there was a last call, however, due to review comments, work continued on the draft. When the PWE3 and L2VPN WGs were merged into the PALS WG, it was reissued as a PALS draft, and updates continued from additional experience from the field and some fresh sets of eyes. Document Quality The document has existed in one form or another since 2005, and has gone through a total of 15 revisions. It has been though WG last call twice (see above for the WG history). There is at least one known implementation that has been deployed in the field for a number of years. Personnel Who is the Document Shepherd for this document?
