This document specifies the Multicast Listener Discovery version 2
(MLDv2) protocol.  MLD is used by an IPv6 router to discover the
presence of multicast listeners on directly attached links and to
discover which multicast addresses are of interest to those
neighboring nodes.  MLDv2 is designed to be interoperable with MLDv1.
 MLDv2 adds the ability for a node to report interest in listening to
packets with a particular multicast address only from specific source
addresses or from all sources except for specific source addresses.

This document updates RFC 2710 and obsoletes RFC 3810.

This document is a product of the Protocols for IP Multicast Working Group of 
the IETF.

This is now an Internet Standard.
