This memo defines a portion of the Management Information Base (MIB) for use with network management protocols. In particular it defines objects for managing the Border Gateway Protocol, Version 4 [RFC4271] (Rekhter, Y., Li, T., and S. Hares, “A Border Gateway Protocol 4 (BGP-4),” January 2006.).

For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410] (Case, J., Mundy, R., Partain, D., and B. Stewart, “Introduction and Applicability Statements for Internet-Standard Management Framework,” December 2002.).
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Structure of Management Information Version 2 (SMIv2),” April 1999.), STD 58, RFC 2579 [RFC2579] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Textual Conventions for SMIv2,” April 1999.) and STD 58, RFC 2580 [RFC2580] (McCloghrie, K., Perkins, D., and J. Schoenwaelder, “Conformance Statements for SMIv2,” April 1999.).

As part of the IETF standardization effort for the BGP-4 protocol, [RFC4273] (Haas, J. and S. Hares, “Definitions of Managed Objects for BGP-4,” January 2006.) was written to address open issues in the previous version of the BGP-4 MIB, [RFC1657] (Willis, S., Burruss, J., and J. Chu, “Definitions of Managed Objects for the Fourth Version of the Border Gateway Protocol (BGP-4) using SMIv2,” July 1994.). However, that RFC was primarily intended to address the base BGP-4 protocol as documented in [RFC4271] (Rekhter, Y., Li, T., and S. Hares, “A Border Gateway Protocol 4 (BGP-4),” January 2006.).
The BGP-4 protocol has greatly increased in scope over the years from its original definition. Scaling mechanisms such as Route Reflection (Bates, T., Chen, E., and R. Chandra, “BGP Route Reflection: An Alternative to Full Mesh Internal BGP (IBGP),” April 2006.) [RFC4456] and Confederations (Traina, P., McPherson, D., and J. Scudder, “Autonomous System Confederations for BGP,” August 2007.) [RFC5065] have been introduced. Multi-protocol extensions (Bates, T., Chandra, R., Katz, D., and Y. Rekhter, “Multiprotocol Extensions for BGP-4,” January 2007.) [RFC4760] were introduced which allowed advertisement of reachability such as IPv6 (Marques, P. and F. Dupont, “Use of BGP-4 Multiprotocol Extensions for IPv6 Inter-Domain Routing,” March 1999.) [RFC2545], MPLS Labeled routes (Rekhter, Y. and E. Rosen, “Carrying Label Information in BGP-4,” May 2001.) [RFC3107], etc.
This MIB addresses several of the deficiencies of the previous BGP-4 MIB and provides an extension mechanism to permit additional MIB modules to be authored without requiring the base BGP-4 MIB to be updated. This is seen as a desirable goal since the BGP-4 protocol continues to receive attention by those wishing to add to its functionality.
In particular, this MIB addresses some specific weaknesses of the previous version:

A feature of this MIB is the recognition that the BGP protocol continues to grow in functionality. The bgpExtensions OID is defined to provide a place for IDR-approved MIB modules for BGP extensions to be added to the bgp MIB subtree.
It is intended that, where possible, that tables added via extensions that add information via additional path attributes use bgpAfPathAttrIndex as a common index, either via INDEX or AUGMENTS.

The bgpPeerAfLocalAddrType/bgpPeerAfLocalAddr/bgpPeerAfLocalPort and bgpPeerAfRemoteAddrType/bgpPeerAfRemoteAddr/bgpPeerAfRemotePort objects may provide a suitable index for monitoring the BGP peering session's TCP session via the TCP-MIB (Raghunarayan, R., “Management Information Base for the Transmission Control Protocol (TCP),” March 2005.) [RFC4022].
Note that conducting BGP peering sessions over transport protocols other than TCP over IP are out of scope of the current BGP specifications.

The following MIB module IMPORTS objects from SNMPv2-SMI [RFC2578] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Structure of Management Information Version 2 (SMIv2),” April 1999.), SNMPv2-TC [RFC2579] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Textual Conventions for SMIv2,” April 1999.), SNMPv2-CONF [RFC2580] (McCloghrie, K., Perkins, D., and J. Schoenwaelder, “Conformance Statements for SMIv2,” April 1999.), INET-ADDRESS-MIB [RFC4001] (Daniele, M., Haberman, B., Routhier, S., and J. Schoenwaelder, “Textual Conventions for Internet Network Addresses,” February 2005.) and SNMP-FRAMEWORK-MIB [RFC3411] (Harrington, D., Presuhn, R., and B.

DESCRIPTION
"Changes from RFC 1657:
1) Fixed the definitions of the notifications
to make them equivalent to their initial
definition in RFC 1269.
2) Added compliance and conformance info.
3) Updated information for the values of
bgpPeerNegotiatedVersion, bgp4PathAttrLocalPref,
bgp4PathAttrCalcLocalPref,
bgp4PathAttrMultiExitDisc,
bgp4PathAttrASPathSegement.
4) Added additional clarification comments where
needed.
5) Noted where objects do not fully reflect
the protocol as Known Issues.
6) Updated the DESCRIPTION for the
bgp4PathAttrAtomicAggregate object.
7) The following objects have had their DESCRIPTION
clause modified to remove the text that suggested
(using 'should' verb) initializing the counter
to zero on a transition to the established state:
bgpPeerInUpdates, bgpPeerOutUpdates,
bgpPeerInTotalMessages, bgpPeerOutTotalMessages
Those implementations that still do this are
still compliant with this new wording.
Applications should not assume counters have
started at zero.

the value specified in
bgpPeerHoldTimeConfigured; the actual
time interval for the KEEPALIVE messages is
indicated by bgpPeerKeepAlive. A
reasonable maximum value for this timer
would be one third of that of
bgpPeerHoldTimeConfigured.
If the value of this object is zero (0),
no periodic KEEPALIVE messages are sent
to the peer after the BGP connection has
been established. The suggested value for
this timer is 30 seconds.

This MIB relates to a system providing inter-domain routing. As such, improper manipulation of the objects represented by this MIB may result in denial of service to a large number of end-users.
There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability:
bgpPeerAdminStatus - Improper change of bgpPeerAdminStatus, from start to stop, can cause significant disruption of the connectivity to those portions of the Internet reached via the applicable remote BGP peer.
bgpPeerConnectRetryInterval - Improper change of this object can cause connections to be disrupted for extremely long time periods when otherwise they would be restored in a relatively short period of time.
bgpPeerHoldTimeConfigured, bgpPeerKeepAliveConfigured - Misconfiguration of these objects can make BGP sessions more fragile and less resilient to denial of service attacks on the inter-domain routing system.
bgpPeerMinASOriginationInterval, bgpPeerMinRouteAdvertisementInterval - Misconfiguration of these objects may adversely affect global Internet convergence of the routes advertised by this BGP speaker. This may result in long-lived routing loops and blackholes for the portions of the Internet that utilize these routes.
Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability:
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.
It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410] (Case, J., Mundy, R., Partain, D., and B. Stewart, “Introduction and Applicability Statements for Internet-Standard Management Framework,” December 2002.), section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.

This document includes an OID, bgpExtensions, which defines a name space for future BGP extensions. IANA is requested to create a new registry for new OIDs under bgpExtensions that will define the root OID of future MIB modules for bgp extensions. The assignment OIDs should be done based upon IDR working group consensus.

This document owes significant thanks over the years to Wayne Tackabury, Susan Hares and the members of the idr and ops-nm mailing lists. This document represents several years of negotiating operational needs, Internet operational security considerations and the sheer messiness of representing the BGP protocol in SMIv2.
I owe particular thanks to Susan Hares as a mentor who let me dive head-first into the world of Internet standards work by saying, "We have this MIB that just needs a little cleanup to advance in the standards process."
