Description: Provides Cisco-specific extensions for monitoring BGP routing protocol implementation, supporting both IPv4 and IPv6 address families.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CISCO-BGP4-MIB with a free 30-day trial of IPNetwork Monitor.

What Is CISCO-BGP4-MIB?

CISCO-BGP4-MIB is a Cisco-specific extension to the IETF's standard BGP4 MIB (RFC 1657), in the routing protocol technology area, adding support for both IPv4 and IPv6 address families to BGP monitoring. It exposes configuration and operational data about BGP peers, local AS number, routing table entries learned via UPDATE messages, and AS path attributes. This makes it central to monitoring the software/protocol status of BGP routing on a device: administrators use it to check peer session state, verify which routes are present in the Adj-RIBs-In, inspect route origin and AS path attributes, and detect route flapping or unexpected route withdrawals that indicate routing instability. It explicitly extends and depends on the IETF BGP4-MIB (RFC 1657) for base object definitions. It is deployed on Cisco routers running BGP in enterprise or service-provider IP networks, particularly where dual-stack IPv4/IPv6 BGP peering is used, making cisco-bgp4-mib a key reference for administrators monitoring BGP session health across address families.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-BGP4-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco routers running BGP

Monitoring Examples

An admin would poll cbgpRouteTable (via cbgpRouteEntry) to inspect a specific route's cbgpRouteAddrPrefix and cbgpRouteAddrPrefixLen alongside cbgpRouteOrigin and cbgpRouteASPathSegment to verify the AS path a prefix took to reach the router. Checking cbgpRoutePeer and cbgpRoutePeerType for a route reveals which peer advertised it, and comparing this against cbgpLocalAs helps validate correct AS numbering in a dual-stack (cbgpRouteAfi/cbgpRouteSafi) deployment. A sudden disappearance of expected routes in cbgpRouteTable for a given peer would flag a BGP session or route-advertisement problem, and cbgpNotifsEnable controls whether related traps are sent via ciscoBgp4MIBObjects.

What Can Be Monitored

BGP peer sessions and peer type
routes learned per peer (Adj-RIBs-In)
route origin and AS path
IPv4/IPv6 address family routes
local AS number
BGP notification/trap enablement

How to Use in IPNetwork Monitor

Example using cbgpPeerAcceptedPrefixes OID:

Select a Cisco routers running BGP as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cbgpPeerAcceptedPrefixes into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the number of accepted route prefixes on this connection, which belong to an address family. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

The value of this object will only determine the KEEPALIVE messages' frequency relative to the value specified in cbgpPeer2HoldTimeConfigured; the actual time interval for the KEEPALIVE messages is indicated by cbgpPeer2KeepAlive. A reasonable maximum value for this timer would be one third of that of cbgpPeer2HoldTimeConfigured.

cbgpRouteTable	1.3.6.1.4.1.9.9.187.1.1.1		not-accessible	This table contains information about routes to destination networks from all BGP4 peers. Since BGP4 can carry routes for multiple Network Layer protocols, this table has the Address Family Identifier(AFI) of the Network Layer protocol as the first index. Further for a given AFI, routes carried by BGP4 are distinguished based on Subsequent Address Family Identifiers(SAFI). Hence that is used as the second index. Conceptually there is a separate Loc-RIB maintained by the BGP speaker for each combination of AFI and SAFI supported by it.
OCT cbgpRouteUnknownAttr	1.3.6.1.4.1.9.9.187.1.1.1.1.19	OCTET STRING	read-only	One or more path attributes not understood by this BGP4 speaker. Size zero (0) indicates the absence of such attribute(s). Octets beyond the maximum size, if any, are not recorded by this object. Each path attribute is a triple of variable length. Attribute Type is a two-octet field that consists of the Attribute Flags octet followed by the Attribute Type Code octet. If the Extended Length bit of the Attribute Flags octet is set to 0, the third octet of the Path Attribute contains the length of the attribute data in octets. If the Extended Length bit of the Attribute Flags octet is set to 1, then the third and the fourth octets of the path attribute contain the length of the attribute data in octets. The remaining octets of the Path Attribute represent the attribute value and are interpreted according to the Attribute Flags and the Attribute Type Code.
ciscoBgp4GlobalGroup	1.3.6.1.4.1.9.9.187.3.2.8			A collection of global objects related to BGP.
ciscoBgp4MIB	1.3.6.1.4.1.9.9.187			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 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.
