The IESG has received a request from the MBONE Deployment WG (mboned) to consider the following document: - 'Mtrace Version 2: Traceroute Facility for IP Multicast' <draft-ietf-mboned-mtrace-v2-21.txt> as Proposed Standard 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 ietf@ietf.org mailing lists by 2017-11-23. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes the IP multicast traceroute facility, named Mtrace version 2 (Mtrace2). Unlike unicast traceroute, Mtrace2 requires special implementations on the part of routers. This specification describes the required functionality in multicast routers, as well as how an Mtrace2 client invokes a query and receives a reply. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-mboned-mtrace-v2/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-mboned-mtrace-v2/ballot/ No IPR declarations have been submitted directly on this I-D.
