I have reviewed this document as part of the security directorate's 
ongoing effort to review all IETF documents being processed by the IESG.
 These comments were written primarily for the benefit of the security 
area directors. Document editors and WG chairs should treat these 
comments just like any other last call comments.

This document describes a tracking function for multicast routers and proxies, intended to reduce latencies and network traffic, among other things.

The document seems well written but the security considerations sections makes vague references to "serious threats" that may be introduced by malicious hosts on the network yet only states that "abuse" can be mitigated by limiting the amount of information a router can store (which seems like a given anyway?). It would be good if the document enumerated the "serious threats" and their mitigations.
