The IESG has approved the following document: - 'PIM Group-to-RP Mapping' (draft-ietf-pim-group-rp-mapping-10.txt) as a Proposed Standard This document is the product of the Protocol Independent Multicast Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pim-group-rp-mapping/ Technical Summary Each PIM-SM router in a Protocol Independent Multicast (PIM) Domain which supports Any Source Multicast (ASM) maintains Group-to-RP mappings which are used to identify a Rendezvous Point(RP) for a specific multicast group. PIM-SM has defined an algorithm to choose a RP from the Group-to-RP mappings learned using various mechanisms. This algorithm does not consider the PIM mode and the mechanism through which a Group-to-RP mapping was learned. This document defines a standard algorithm to deterministically choose between several group-to-rp mappings for a specific group. This document first explains the requirements to extend the Group-to-RP mapping algorithm and then proposes the new algorithm. Working Group Summary WG consensus appears sound. There is consensus within the PIM WG to publish the document. While it has not received wild working group involvement, the participation has been active with individuals from a variety of vendors and providers. Document Quality The document has undergone thorough review within IETF's Multicast community. Personnel Mike McBride (mcbride@cisco.com) is the Document Shepherd. Adrian Farrel (adrian.farrel@huawei.com) is the Responsible AD.
