CISCO-IETF-IPMROUTE-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

    DESCRIPTION
            "Address family independent MIB module for management
             IP Multicast routing, but independent of the specific 
             multicast routing protocol in use.

             This MIB module is based on RFC 2932 with additional 
             MIB objects to make it a address family independent MIB. 
             This Cisco MIB was created due to non availability 
             of RFC or an Internet Draft which can provide address 
             family independent MIB for IP Multicast Routing. This 
             MIB may later be deprecated with a stable RFC or an 
             Internet Draft 


             This MIB module contains two scalars and five 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 next-hops for the routing IP 
                 multicast datagrams. Each entry is one of a list 
                 of next-hops on outgoing interfaces for particular
                 sources sending to a particular multicast group 
                 address.

            (3)  The IP Multicast Routing Interface Table containing
                 multicast routing information specific to interfaces.

            (4)  The IP Multicast Scope Boundary Table containing the
                 boundaries configured for multicast scopes.

            (5)  The IP Multicast Scope Name Table containing
                 human-readable names of multicast scope.
