Description: Defines objects for managing Virtual Private LAN Service instances using BGP as the signaling protocol for autodiscovery and signaling.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is VPLS-BGP-DRAFT-01-MIB?

VPLS-BGP-DRAFT-01-MIB is an IETF draft MIB module (predecessor to what became part of the L2VPN/VPLS MIB work tied to RFC 4761) covering Virtual Private LAN Service instances that use BGP for autodiscovery and pseudowire signaling on provider-edge routers. It exposes configuration and status data for VPLS instances, their BGP-based peer discovery state, and the pseudowires that stitch customer sites together over an MPLS core. In monitoring terms it is used to check the operational status of VPLS service instances and their BGP signaling sessions rather than classic hardware health, though the underlying router's overall reachability and uptime remain relevant context. It explicitly depends on BGP (as extended by RFC 4761) and on an underlying pseudowire/MPLS infrastructure, so it is typically deployed alongside PW-MIB, MPLS MIBs, and standard BGP MIBs. It is used in service-provider networks on PE routers that terminate multipoint Ethernet VPN services for enterprise customers. Network engineers evaluating or troubleshooting this functionality can download the VPLS-BGP-DRAFT-01-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in VPLS-BGP-DRAFT-01-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

Provider Edge (PE) router
vendor-neutral, standards-based MIB, not tied to a specific manufacturer

Monitoring Examples

The MIB extractor found no concrete object or table names in this module, so no specific OIDs can be cited; based on the module description, an operator would expect it to expose per-VPLS-instance configuration and BGP autodiscovery/signaling status objects. A realistic use would be polling a VPLS instance's discovery and pseudowire binding state to confirm all expected remote PE routers have been discovered via BGP, flagging a service outage if an expected peer drops out. Because the actual object names were not available for grounding, any more specific detail here would be speculative.

What Can Be Monitored

VPLS instance configuration
BGP autodiscovery status
pseudowire binding state
VPLS service reachability

The initial version of this MIB module was published in RFC XXXX. -- RFC Editor: Please replace XXXX with RFC number & remove -- this note. For full legal notices see the RFC itself or see: http://www.ietf.org/copyrights/ianamib.html This MIB module contains managed object definitions for BGP signalled Virtual Private LAN Services as in [RFC4761] This MIB module enables the use of any underlying PseudoWire network.
jnxVplsBgpObjects	1.3.6.1.4.1.2636.5.10.1
jnxVplsBgpConfigTable	1.3.6.1.4.1.2636.5.10.1.1		not-accessible	This table specifies information for configuring and monitoring BGP specific parameters for Virtual Private Lan Services(VPLS).
jnxVplsBgpConfigEntry	1.3.6.1.4.1.2636.5.10.1.1.1		not-accessible	A row in this table represents BGP specific information for Virtual Private Lan Service(VPLS) in a packet network. It is indexed by jnxVplsConfigIndex, which uniquely identifies a single instance of a VPLS service. A row is automatically created when a VPLS service is configured using BGP signalling. None of the read-create objects values can be changed when jnxVplsRowStatus is in the active(1) state. Changes are allowed when the jnxVplsRowStatus is in notInService(2) or notReady(3) states only. If the operator need to change one of the values for an active row the jnxVplsConfigRowStatus should be first changed to notInService(2), the objects may be changed now, and later to active(1) in order to re-initiate the signaling process with the new values in effect.
U32 jnxVplsBgpConfigVERangeSize	1.3.6.1.4.1.2636.5.10.1.1.1.1	Unsigned32	read-only	Specifies the size of the range of VE ids in this VPLS service. This number controls the size of the label block advertised for this VE by the PE. A value of 0 indicates that the range is not configured and the PE derives the range value from received advertisements from other PEs.
jnxVplsBgpVETable	1.3.6.1.4.1.2636.5.10.1.2		not-accessible	This table associates VPLS Edge devices to a VPLS service
jnxVplsBgpVEEntry	1.3.6.1.4.1.2636.5.10.1.2.1		not-accessible	An entry in this table is created for each VE Id configured on a PE for a particular VPLS service instance.
U32 jnxVplsBgpVEId	1.3.6.1.4.1.2636.5.10.1.2.1.1	Unsigned32	not-accessible	A secondary index identifying a VE within an instance of a VPLS service.
STR jnxVplsBgpVEName	1.3.6.1.4.1.2636.5.10.1.2.1.2	SnmpAdminString	read-only	Descriptive name for the site or u-PE assciated with this VE Id.
U32 jnxVplsBgpVEPreference	1.3.6.1.4.1.2636.5.10.1.2.1.3	Unsigned32	read-only	Specifies the preference of the VE Id on this PE if the site is multi-homed and VE Id is re-used.
ROW jnxVplsBgpVERowStatus	1.3.6.1.4.1.2636.5.10.1.2.1.5	RowStatus	read-only	This variable is used to create, modify, and/or delete a row in this table. When a row in this table is in active(1) state, no objects in that row can be modified except jnxVplsBgpSiteRowStatus.
STO jnxVplsBgpVEStorageType	1.3.6.1.4.1.2636.5.10.1.2.1.6	StorageType	read-only	This variable indicates the storage type for this row.
jnxVplsBgpPwBindTable	1.3.6.1.4.1.2636.5.10.1.3		not-accessible	This table provides BGP specific information for an association between a VPLS service and the corresponding Pseudo Wires. A service can have more than one Pseudo Wire association. Pseudo Wires are defined in the pwTable.
jnxVplsBgpPwBindEntry	1.3.6.1.4.1.2636.5.10.1.3.1		not-accessible	Each row represents an association between a VPLS instance and one or more Pseudo Wires defined in the pwTable. Each index is unique in describing an entry in this table. However both indexes are required to define the one to many association of service to pseudowire. An entry in this table in instantiated only when BGP signalling is used to configure VPLS service. Each entry in this table provides BGP specific information for the VPlS represented by jnxVplsConfigIndex.
U32 jnxVplsBgpPwBindLocalVEId	1.3.6.1.4.1.2636.5.10.1.3.1.1	Unsigned32	read-only	Identifies the local VE that this Pseudo Wire is associated with.
U32 jnxVplsBgpPwBindRemoteVEId	1.3.6.1.4.1.2636.5.10.1.3.1.2	Unsigned32	read-only	Identifies the remote VE that this Pseudo Wire is associated with.
