    DESCRIPTION

            "The MIB module for management of IP Multicast, including

            multicast routing, data forwarding, and data reception.

            Copyright (C) The IETF Trust (2007).  This version of this

            MIB module is part of RFC 5132; see the RFC itself for full

            legal notices."

    REVISION     "200711090000Z" -- 9 November 2007

    DESCRIPTION  "Initial version, published as RFC 5132.

                 This MIB module obsoletes IPMROUTE-STD-MIB defined by

                 [RFC2932].  Changes include the following:

                 o  This MIB module includes support for IPv6 addressing

                    and the IPv6 scoped address architecture.  [RFC2932]

                    supported only IPv4.

                 o  This MIB module allows several multicast protocols

                    to perform routing on a single interface, where

                    [RFC2932] assumed each interface supported at most

                    one multicast routing protocol.  Multicast routing

                    protocols are now per-route, see

                    ipMcastRouteProtocol.

                 o  This MIB module includes objects that are not

                    specific to multicast routing.  It allows management

                    of multicast function on systems that do not perform

                    routing, whereas [RFC2932] was restricted to

                    multicast routing.

                 o  This MIB module includes a table of Source-Specific

                    Multicast (SSM) address ranges to which SSM

                    semantics [RFC3569] should be applied.

                 o  This MIB module includes a table of local

                    applications that are receiving multicast data.

                 o  This MIB module includes a table of multicast scope

                    zones."
