    Status of this Memo
    
    This document is an Internet Draft.  Internet Drafts are working
    documents of the Internet Engineering Task Force (IETF), its Areas, and
    its Working Groups.  Note that other groups may also distribute working
    documents as Internet Drafts.
    
    Internet Drafts are valid for a maximum of six months and may be
    updated, replaced, or obsoleted by other documents at any time.  It is
    inappropriate to use Internet Drafts as reference material or to cite
    them other than as a "work in progress".
    
    
    1.  Introduction
    
    This memo defines an experimental portion of the Management Information
    Base (MIB) for use with network management protocols in the Internet
    community.  In particular, it describes managed objects used for
    managing IP Multicast Routing [5], independent of the specific multicast
    routing protocol [6,7] in use.  Managed objects specific to particular
    multicast routing protocols are specified elsewhere.
    
    
    
    2.  The SNMPv2 Network Management Framework
    
    The SNMPv2 Network Management Framework consists of four major
    components.  They are:
    
    o    RFC 1442 [1] which defines the SMI, the mechanisms used for
         describing and naming objects for the purpose of management.
    
    
    
    
    
    
    
    
    
    
    
    
    Draft                   IP Multicast Routing MIB               July 1994
    
    
    o    STD 17, RFC 1213 [2] defines MIB-II, the core set of managed
         objects for the Internet suite of protocols.
    
    o    RFC 1445 [3] which defines the administrative and other
         architectural aspects of the framework.
    
    o    RFC 1448 [4] which defines the protocol used for network access to
         managed objects.
    
    The Framework permits new objects to be defined for the purpose of
    experimentation and evaluation.
    
    
    2.1.  Object Definitions
    
    Managed objects are accessed via a virtual information store, termed the
    Management Information Base or MIB.  Objects in the MIB are defined
    using the subset of Abstract Syntax Notation One (ASN.1) defined in the
    SMI.  In particular, each object type is named by an OBJECT IDENTIFIER,
    an administratively assigned name.  The object type together with an
    object instance serves to uniquely identify a specific instantiation of
    the object.  For human convenience, we often use a textual string,
    termed the descriptor, to refer to the object type.
    
    
    3.  Overview
    
    This MIB module contains one scalar and three tables.  The tables are:
    
    (1)  the IP Multicast Route Table containing multicast routing
         information for IP datagrams sent by particular sources to the IP
         multicast groups known to a router;
    
    (2)  the IP Multicast Routing Next Hop Table containing information on
         the outgoing interfaces and next hops for the routing IP multicast
         datagrams.  Each entry is one of a list of outgoing interface and
         next hops for a particular source and multicast group address; and
    
    (3)  the Multicast Routing Interface Table containing multicast routing
         information specific to interfaces.
