MPLS-FRR-GENERAL-STD-MIB
AI MIB Summary
The MPLS-FRR-GENERAL-STD-MIB module defines standard SNMP objects for monitoring MPLS Traffic Engineering Fast Reroute (FRR) state transitions, backup tunnel status, and protection switching events as specified in RFC 4090. It enables network operators to track local repair mechanisms, including bypass tunnel availability and primary/backup path failover counters, across compliant MPLS-capable routers.

mplsFrrGeneralObjects OBJECT IDENTIFIER .1.3.6.1.2.1.202.1 |
mplsFrrGeneralProtectionMethodIndicates which protection method is to be used for fast reroute on this device. Some devices may require a reboot if this variable is to take effect after being modified.rw Enumeration .1.3.6.1.2.1.202.1.1 |
mplsFrrGeneralIngressTunnelInstancesThe number of tunnel instances for either detour LSPs or bypass tunnels for which this LSR is the ingress.ro Counter32 .1.3.6.1.2.1.202.1.2 |
mplsFrrGeneralConstraintsTableThis table shows detour LSP or bypass tunnel setup constraints. SEQUENCE OF MplsFrrGeneralConstraintsEntry .1.3.6.1.2.1.202.1.3 |
mplsFrrGeneralConstraintsEntryAn entry in this table represents detour LSP or bypass tunnel setup constraints for an interface or link to be protected by detour LSPs or a bypass tunnel. Once the LSP or tunnel instance to be protected is identified in the mplsTunnelTable, the corresponding mplsTunnelIfIndex value of that tunnel can be used to get the ifIndex of the underlying physical interface using the ifStackTable. That ifIndex of the underlying physical interface will be used as mplsFrrGeneralConstraintsIfIndexOrZero in this table to protect the LSPs or tunnel instances determined earlier. It is recommended that ifIndex persistence be enabled across re-initializations. If persistence is not implemented, then the value of mplsFrrGeneralConstraintsIfIndexOrZero in this table cannot be guaranteed across restarts and all entries in this table MUST NOT be persistent, or the values of mplsFrrGeneralConstraintsIfIndexOrZero MUST be reconstructed on restart. SNMP engines must only allow entries in this table to be created for tunnel instances that require fast reroute as indicated by the presence of the FAST_REROUTE object in the signaling for the LSP in question. An entry in this table can be created only if a corresponding entry in mplsTunnelTable exists with the same mplsTunnelIndex as mplsFrrGeneralConstraintsTunnelIndex. Entries in this table are deleted when the corresponding entries in mplsTunnelTable are deleted. It is recommended that entries in this table be persistent across reboots. Entries indexed with mplsFrrGeneralConstraintsIfIndexOrZero and set to 0 apply to all interfaces on this device for which the FRR feature can operate. If the mplsTunnelInstance object is set to a value of 0, it indicates that the mplsTunnelEntry contains a tunnel ingress. This is typically how configuration of this feature is performed on devices where the actual protection LSP used is left up to the protecting tunnel. However, in cases where static configuration is possible, any valid tunnel instance is possible; however, it is strongly RECOMMENDED that the instance index SHOULD use the following convention to identify backup LSPs: - lower 16 bits : protected tunnel instance - higher 16 bits: must be all zeros MplsFrrGeneralConstraintsEntry .1.3.6.1.2.1.202.1.3.1 |
mplsFrrGeneralConstraintsIfIndexOrZeroUniquely identifies an interface that a fast-reroute protection tunnel is configured to potentially protect in the event of a fault. Entries with this index set to 0 indicate that the configured protection tunnel protects all interfaces on this device (i.e., node protection). InterfaceIndexOrZero (IF-MIB) .1.3.6.1.2.1.202.1.3.1.1 |
mplsFrrGeneralConstraintsTunnelIndexUniquely identifies a tunnel in the mplsTunnelTable that is configured to possibly protect the interface(s) specified by mplsFrrGeneralConstraintsIfIndexOrZero in the event of a fault. MplsTunnelIndex (MPLS-TC-STD-MIB) .1.3.6.1.2.1.202.1.3.1.2 |
mplsFrrGeneralConstraintsTunnelInstanceUniquely identifies an existing instance of this tunnel for which fast reroute is requested. Note that a value of 0 indicates that the configuration points at a tunnel head (as specified in RFC 3812). This is typically how configuration of this feature is performed on devices where the actual protection LSP used is left up to the protecting tunnel. However, in cases where static configuration is possible, any valid tunnel instance is permissible. In these cases, it is recommended that the instance index follow the following convention so as to make identification of backup LSPs easier: - lower 16 bits : protected tunnel instance - higher 16 bits: must be all zeros MplsTunnelInstanceIndex (MPLS-TC-STD-MIB) .1.3.6.1.2.1.202.1.3.1.3 |
mplsFrrGeneralConstraintsProtectionTypeIndicates type of the resource protection: linkProtection(1) indicates that this tunnel is set up to protect a particular link's resources. nodeProtection(2) indicates that this tunnel is set up to protect an entire node from failure.rw Enumeration .1.3.6.1.2.1.202.1.3.1.4 |
mplsFrrGeneralConstraintsSetupPrioIndicates the setup priority of the detour LSP or bypass tunnel.rw Unsigned32 .1.3.6.1.2.1.202.1.3.1.5 |
mplsFrrGeneralConstraintsHoldingPrioIndicates the holding priority for the detour LSP or bypass tunnel.rw Unsigned32 .1.3.6.1.2.1.202.1.3.1.6 |
mplsFrrGeneralConstraintsInclAnyAffinityIndicates the include-any link constraint for the detour LSP or bypass tunnel. A link satisfies the include-any constraint if and only if the constraint is zero, or the link and the constraint have a resource class in common.rw MplsTunnelAffinity (MPLS-TC-STD-MIB) .1.3.6.1.2.1.202.1.3.1.7 |
mplsFrrGeneralConstraintsInclAllAffinityIndicates the include-all link constraint for the detour LSP or bypass tunnel. A link satisfies the include-all constraint if and only if the link contains all of the administrative groups specified in the constraint.rw MplsTunnelAffinity (MPLS-TC-STD-MIB) .1.3.6.1.2.1.202.1.3.1.8 |
mplsFrrGeneralConstraintsExclAnyAffinityIndicates the exclude-any link constraint for the detour LSP or bypass tunnel. A link satisfies the exclude-any constraint if and only if the link contains none of the administrative groups specified in the constraint.rw MplsTunnelAffinity (MPLS-TC-STD-MIB) .1.3.6.1.2.1.202.1.3.1.9 |
mplsFrrGeneralConstraintsHopLimitThe maximum number of hops that the detour LSP or bypass tunnel may traverse.rw Unsigned32 .1.3.6.1.2.1.202.1.3.1.10 |
mplsFrrGeneralConstraintsBandwidthThe maximum bandwidth specifically reserved for a detour LSP or bypass tunnel, in units of thousands of bits per second (kbps). Note that setting this value to 0 indicates best-effort treatment.rw MplsBitRate UNITS "kilobits per second" .1.3.6.1.2.1.202.1.3.1.11 |
mplsFrrGeneralConstraintsStorageTypeThe storage type for this configuration entry. Conceptual rows having the value 'permanent' need not allow write access to any columnar objects in the row.rw StorageType (SNMPv2-TC) .1.3.6.1.2.1.202.1.3.1.12 |
mplsFrrGeneralConstraintsRowStatusThis object 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 mplsFrrGeneralConstraintsRowStatus and mplsFrrGeneralConstraintsStorageType.rw RowStatus (SNMPv2-TC) .1.3.6.1.2.1.202.1.3.1.13 |
mplsFrrGeneralTunnelARHopTableThis table sparsely extends mplsTunnelARHopTable defined in the MPLS-TE-STD-MIB module with fast-reroute objects. These objects specify the status of local protection, including availability and active use, on a per-hop basis, of hops traversed by a protected tunnel. SEQUENCE OF MplsFrrGeneralTunnelARHopEntry .1.3.6.1.2.1.202.1.4 |
mplsFrrGeneralTunnelARHopEntryThis entry contains fast-reroute protection status of a single protected tunnel hop. MplsFrrGeneralTunnelARHopEntry .1.3.6.1.2.1.202.1.4.1 |
mplsFrrGeneralTunnelARHopSessionAttributeFlagsThis object indicates the desired values for the associated SESSION_ATTRIBUTE flags. Note that since this object is a BITS type, the bits may be set to indicate various desired combinations of the SESSION_ATTRIBUTE flags. If SESSION_ATTRIBUTE flags are not supported, then this object contains the value of arHopSessionAttrFlagsUnsupported(0).ro Bits .1.3.6.1.2.1.202.1.4.1.1 |
mplsFrrGeneralTunnelARHopRROSubObjectFlagsThis object indicates the flags that are currently in use by the associated Record Route Object (RRO) sub-object. Note that since this object is a BITS type, the bits may be set to indicate various combinations of the flags. If the RRO sub-object is not supported, then this object contains the value of arHopRROSubObjectFlagsUnsupported(0).ro Bits .1.3.6.1.2.1.202.1.4.1.2 |
