The base Multicast VPN (MVPN) specifications (RFCs 6513 and 6514)
provide procedures to allow a multicast ingress node to invoke
"explicit tracking" for a multicast flow or set of flows, thus
learning the egress nodes for that flow or set of flows.  However,
the specifications are not completely clear about how the explicit
tracking procedures work in certain scenarios.  This document
provides the necessary clarifications.  It also specifies a new,
optimized explicit-tracking procedure.  This new procedure allows an
ingress node, by sending a single message, to request explicit
tracking of each of a set of flows, where the set of flows is
specified using a wildcard mechanism.  This document updates RFCs
6514, 6625, 7524, 7582, and 7900.

This document is a product of the BGP Enabled Services Working Group of the 
IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
