CISCO-BGP4-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
                "An extension to the IETF BGP4 MIB module defined in 
                RFC 1657.
                               
                Following is the terminology associated with Border
                Gateway Protocol(BGP).
                   
                UPDATE message
                    UPDATE messages are used to transfer routing 
                    information between BGP peers. An UPDATE message 
                    is used to advertise a single feasible route to a
                    peer, or to withdraw multiple unfeasible routes 
                    from service.                 

                Adj-RIBs-In 
                   The Adj-RIBs-In store routing information that has
                   been learned from inbound UPDATE messages. Their 
                   contents represent routes that are available as an 
                   input to the Decision Process.

                Loc-RIB(BGP table) 
                   The Loc-RIB contains the local routing information
                   that the BGP speaker has selected by applying its 
                   local policies to the routing information contained 
                   in its Adj-RIBs-In.

                Adj-RIBs-Out 
                   The Adj-RIBs-Out store the information that the
                   local BGP speaker has selected for advertisement to 
                   its peers. The routing information stored in the 
                   Adj-RIBs-Out will be carried in the local BGP 
                   speaker's UPDATE messages and advertised to its
                   peers.
                
                Path Attributes
                   A variable length sequence of path attributes is 
                   present in every UPDATE. Each path attribute is a 
                   triple <attribute type, attribute length, 
                   attribute value> of variable length. 
               
                Network Layer Reachability Information(NLRI)
                   A variable length field present in UPDATE messages
                   which contains a list of Network Layer address 
                   prefixes. 

                Address Family Identifier(AFI) 
                   Primary identifier to indicate the type of the 
                   Network Layer Reachability Information(NLRI) being 
                   carried.

                Subsequent Address Family Identifier(SAFI) 
                   Secondary identifier to indicate the type of the 
                   Network Layer Reachability Information(NLRI) being 
                   carried."
