Description: Manages IETF provider-provisioned MPLS VPN instance, VRF, and interface objects.

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 MPLS-VPN-MIB?

MPLS-VPN-MIB is an IETF standards-based MIB (RFC 3031-aligned) for managing Multiprotocol Label Switching BGP/MPLS Virtual Private Network instances on provider-edge routers. It exposes configuration and status data about VRFs (VPN Routing and Forwarding instances), including how many VRFs are configured versus active, which interfaces are bound to VPNs, route distribution protocols, and route-limit thresholds. It supports monitoring device operational/configuration status by exposing counts of configured versus active VRFs and per-interface VPN classification and label-edge type, which reveals provisioning mismatches or interfaces that failed to come up in a VPN context; it also defines notifications for threshold and state events. It is explicitly built on MPLS and BGP standards (RFC 3031) and is commonly used together with MPLS-LSR-MIB and BGP4-MIB for complete PE-router visibility. Engineers troubleshooting VRF provisioning problems often consult the MPLS-VPN-MIB reference for the exact indexing of mplsVpnIfConfTable and the associated threshold notification objects. It is deployed on service-provider MPLS/BGP PE routers offering Layer 3 VPN services to enterprise customers.

IPNetwork Monitor allows you to monitor SNMP objects defined in MPLS-VPN-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
MPLS/BGP provider-edge (PE) routers

Monitoring Examples

An operator polls mplsVpnConfiguredVrfs against mplsVpnActiveVrfs to detect VRFs that are defined but not operationally active, indicating a provisioning or routing protocol failure. Walking mplsVpnIfConfTable/mplsVpnIfConfEntry (indexed by mplsVpnIfConfIndex) shows mplsVpnIfVpnClassification and mplsVpnIfVpnRouteDistProtocol per interface, useful for confirming a customer-facing interface is correctly bound to its VRF. mplsVpnVrfConfMaxPossibleRoutes and mplsVpnVrfConfRouteMaxThreshTime govern route-limit notifications (mplsVpnNotifications) that fire when a VRF approaches its configured route ceiling.

What Can Be Monitored

configured vs. active VRF counts
connected VPN interfaces
per-interface VPN classification
route distribution protocol per VRF
VRF route-count threshold status

OIDs

OID symbolic	OID numeric	Type	Access	Description
NTF mplsNumVrfRouteMaxThreshExceeded	1.3.6.1.3.118.0.4			This notification is generated when the number of routes contained by the specified VRF reaches or attempts to exceed the maximum allowed value as indicated by mplsVrfMaxRouteThreshold. In cases where mplsVpnVrfConfHighRouteThreshold is set to the same value as mplsVpnVrfConfMaxRoutes, mplsVpnVrfConfHighRouteThreshold need not be exceeded; rather, just reached for this notification to be issued. Note that mplsVpnVrfConfRouteMaxThreshTime denotes the interval at which the this notification will be re-issued after the maximum value has been exceeded (or reached if mplsVpnVrfConfMaxRoutes and mplsVpnVrfConfHighRouteThreshold are equal) and the initial notification has been issued. This value is intended to prevent continuous generation of notifications by an agent in the event that routes are continually added to a VRF after it has reached its maximum value. The default value is 10 minutes. If this value is set to 0, the agent should only issue a single notification at the time that the maximum threshold has been reached, and should not issue any more notifications until the value of routes has fallen below the configured threshold value.
NTF mplsNumVrfRouteMidThreshExceeded	1.3.6.1.3.118.0.3			This notification is generated when the number of routes contained by the specified VRF exceeds the value indicated by mplsVrfMidRouteThreshold. A single notification MUST be generated when this threshold is exceeded, and no other notifications of this type should be issued until the value of mplsVpnVrfPerfCurrNumRoutes has fallen below that of mplsVpnVrfConfMidRouteThreshold.
NTF mplsNumVrfSecIllglLblThrshExcd	1.3.6.1.3.118.0.5			This notification is generated when the number of illegal label violations on a VRF as indicated by mplsVpnVrfSecIllegalLblVltns has exceeded mplsVpnVrfSecIllegalLblRcvThrsh. The threshold is not included in the varbind here because the value of mplsVpnVrfSecIllegalLblVltns should be one greater than the threshold at the time this notification is issued.

U32 mplsVpnVrfRouteTargetIndex	1.3.6.1.3.118.1.2.3.1.2	Unsigned32	not-accessible	Auxiliary index for route-targets configured for a particular VRF.
ROW mplsVpnVrfRouteTargetRowStatus	1.3.6.1.3.118.1.2.3.1.6	RowStatus	read-create	Row status for this entry.
mplsVpnVrfRouteTargetTable	1.3.6.1.3.118.1.2.3		not-accessible	This table specifies per-VRF route target association. Each entry identifies a connectivity policy supported as part of a VPN.
INT mplsVpnVrfRouteTargetType	1.3.6.1.3.118.1.2.3.1.3	INTEGER	not-accessible	The route target export distribution type.
U32 mplsVpnVrfRouteTos	1.3.6.1.3.118.1.4.1.1.5	Unsigned32	not-accessible	The IP TOS Field is used to specify the policy to be applied to this route. The encoding of IP TOS is as specified by the following convention. Zero indicates the default path if no more specific policy applies. +-----+-----+-----+-----+-----+-----+-----+-----+ \| \| \| \| \| PRECEDENCE \| TYPE OF SERVICE \| 0 \| \| \| \| \| +-----+-----+-----+-----+-----+-----+-----+-----+ IP TOS IP TOS Field Policy Field Policy Contents Code Contents Code 0 0 0 0 ==> 0 0 0 0 1 ==> 2 0 0 1 0 ==> 4 0 0 1 1 ==> 6 0 1 0 0 ==> 8 0 1 0 1 ==> 10 0 1 1 0 ==> 12 0 1 1 1 ==> 14 1 0 0 0 ==> 16 1 0 0 1 ==> 18 1 0 1 0 ==> 20 1 0 1 1 ==> 22 1 1 0 0 ==> 24 1 1 0 1 ==> 26 1 1 1 0 ==> 28 1 1 1 1 ==> 30.
INT mplsVpnVrfRouteType	1.3.6.1.3.118.1.4.1.1.9	INTEGER	read-create	The type of route. Note that local(3) refers to a route for which the next hop is the final destination; remote(4) refers to a route for that the next hop is not the final destination. Routes which do not result in traffic forwarding or rejection should not be displayed even if the implementation keeps them stored internally. reject (2) refers to a route which, if matched, discards the message as unreachable. This is used in some protocols as a means of correctly aggregating routes.
mplsVpnVrfSecEntry	1.3.6.1.3.118.1.2.6.1		not-accessible	An entry in this table is created by an LSR for every VRF capable of supporting MPLS/BGP VPN. Each entry in this table is used to indicate security-related information for each VRF entry.

mplsVpnVrfSecTable	1.3.6.1.3.118.1.2.6		not-accessible	This table specifies per MPLS/BGP VPN VRF Table security features.
mplsVpnVrfTable	1.3.6.1.3.118.1.2.2		not-accessible	This table specifies per-interface MPLS/BGP VPN VRF Table capability and associated information. Entries in this table define VRF routing instances associated with MPLS/VPN interfaces. Note that multiple interfaces can belong to the same VRF instance. The collection of all VRF instances comprises an actual VPN.
VPN mplsVpnVrfVpnId	1.3.6.1.3.118.1.2.2.1.2	VPNId	read-create	The VPN ID as specified in RFC 2685. If a VPN ID as not been specified for this VRF, then this variable SHOULD be set to an empty string.
NTF mplsVrfIfDown	1.3.6.1.3.118.0.2			This notification is generated when: a. The ifOperStatus of an interface associated with a VRF changes to the down(1) state. b. When an interface with ifOperStatus = up(1) state is disassociated with a VRF.
NTF mplsVrfIfUp	1.3.6.1.3.118.0.1			This notification is generated when: a. The ifOperStatus of an interface associated with a VRF changes to the up(1) state. b. When an interface with ifOperStatus = up(1) is associated with a VRF.
