When the value of isisSummAddress (excluding the zone index, if one is present) is x, then the bitwise logical-AND of x with the value of the mask formed from the corresponding index object isisSummAddrPrefixLen MUST be equal to x. If not, then the index pair is not consistent, and an inconsistentName error must be returned on SET or CREATE requests.

Routes that fall into the ranges specified are announced as is, without being summarized. Routes that do not match a summary mask are not announced.

OBJECT-TYPE

Each entry contains one configured IP summary address to manage leaking L2 addresses into L1. Dynamically created rows MUST survive an agent reboot. Implementers need to be aware that if the total number of elements (octets or sub-identifiers) in isisRedistributeAddrAddress and isisRedistributeAddrPrefixLen is too great, then OIDs of column instances in this table will have more than 128 subidentifiers and cannot be accessed using SNMPv1, SNMPv2c, or SNMPv3.

When the value of isisRedistributeAddrAddress (excluding the zone index, if one is present) is x, then the bitwise logical-AND of x with the value of the mask formed from the corresponding index object isisRedistributeAddrPrefixLen MUST be equal to x. If not, then the index pair is not consistent, and an inconsistentName error must be returned on SET or CREATE requests.

OBJECT-TYPE

The state of the database at this level. The value 'off' indicates that IS-IS is not active at this level. The value 'on' indicates that IS-IS is active at this level and is not overloaded. The value 'waiting' indicates a database that is low on an essential resource, such as memory. The administrator may force the state to 'overloaded' by setting the object isisSysLevelSetOverload. If the state is 'waiting' or 'overloaded', we originate LSPs with the overload bit set.

OBJECT-TYPE

Administratively set the overload bit for the level. The overload bit MUST continue to be set if the implementation runs out of memory, independent of this variable. It may also be set manually independent of this variable, using the isisSysLevelSetOverloadUntil object.

OBJECT-TYPE

If this object is non-zero, the overload bit is set at this level when the isisSysAdminState variable goes to state 'on' for this Intermediate System. The overload bit remains set for isisSysLevelSetOverloadUntil seconds. When isisSysLevelSetOverloadUntil seconds have elapsed, the overload flag remains set if the implementation has run out of memory, or if it is set manually using the isisSysLevelSetOverload object. If isisSysLevelSetOverload is false, the system clears the overload bit when isisSysLevelSetOverloadUntil seconds have elapsed, if the system has not run out of memory.

Which style of metric do we consider in our SPF computation at this level?

OBJECT-TYPE

Do we do Traffic Engineering at this level?

OBJECT-IDENTITY

OBJECT-TYPE

This object is used to assist a management application in creating new rows in the isisCircTable. If it is possible to create a new instance of isisCircEntry, then this object will contain a non-zero value that is not in use as the index of any row in the isisCircTable. The network manager reads the value of this object and then (if the value read is non-zero) attempts to create the corresponding instance of isisCircEntry. If the set request fails with the code 'inconsistentValue', then the process must be repeated; if the set request succeeds, then the agent will change the value of this object according to an implementation-specific algorithm.

OBJECT-TYPE

An isisCircEntry exists for each circuit configured for Integrated IS-IS on this system. Dynamically created rows MUST survive an agent reboot.

OBJECT-TYPE

An index used to uniquely identify this circuit. When creating a row in this table, the isisNextCircIndex object should be retrieved, and its value should be specified as the value of this index using a SET operation. A retrieved value of zero(0) indicates that no rows can be created at this time.

Thus, if the isisSysTpe is level2 and the isisCircLevelType for a circuit is level1, the circuit will not send or receive IS-IS packets. This object follows the ReplaceOnlyWhileDisabled behavior.

OBJECT-TYPE

Should we include this interface in LSPs, even if it is not running the IS-IS Protocol?

OBJECT-TYPE

Is this port a member of a mesh group, or is it blocked? Circuits in the same mesh group act as a virtual multiaccess network. LSPs seen on one circuit in a mesh group will not be flooded to another circuit in the same mesh group.

OBJECT-TYPE

Circuits in the same mesh group act as a virtual multiaccess network. LSPs seen on one circuit in a mesh group will not be flooded to another circuit in the same mesh group. If isisCircMeshGroupEnabled is inactive or blocked, this value is ignored.

For broadcast circuits, the value is used to generate the LAN ID that will be used if this Intermediate System is elected as the Designated IS on this circuit. The value is required to differ on LANs where the Intermediate System is the Designated Intermediate System.

OBJECT-TYPE

On a point-to-point circuit with a fully initialized adjacency to a peer IS, the value of this object is the circuit ID negotiated during adjacency initialization. On a point to point circuit without such an adjacency, the value is the concatenation of the local system ID and the one-byte isisCircLevelIDOctet for this circuit, i.e., the value that would be proposed for the circuit ID. On other circuit types, the value returned is the zero- length OCTET STRING.

OBJECT-TYPE

The type of this IP Reachable Address. Those of type manual are created by the network manager. Those of type automatic are created through propagation of routing information from another routing protocol. This object follows the ManualOrAutomatic behavior.

OBJECT-TYPE

The state of this IP Reachable Address. This object follows the ExistenceState and ManualOrAutomatic behaviors. Support for 'createAndWait' and 'notInService' is not required. A row entry cannot be modified when the value of this object is 'active'.

OBJECT-TYPE

The administrative state of the IP Reachable Address. This object follows the IsisAdminState and ManualOrAutomatic behaviors.

OBJECT-TYPE

The metric value for reaching the specified destination over this circuit. This object follows the ManualOrAutomatic behavior.

OBJECT-TYPE

Indicates whether the metric is internal or external. This object follows the ManualOrAutomatic behavior.

OBJECT-TYPE

The wide metric value for reaching the specified destination over this circuit. This object follows the ManualOrAutomatic behavior.

OBJECT-TYPE

The SNPA Address to which a PDU may be forwarded in order to reach a destination that matches this IP Reachable Address. This object follows the ManualOrAutomatic behavior.

OBJECT-TYPE

The origin of this route.

OBJECT-IDENTITY

OBJECT-TYPE

The table of LSP Headers.

OBJECT-TYPE

Each entry provides a summary describing an LSP currently stored in the system. Dynamically learned rows will not survive an agent reboot.

OBJECT-TYPE

At which level does this LSP appear?

OBJECT-TYPE

The 8-byte LSP ID for this Link State PDU.

OBJECT-TYPE

The sequence number for this LSP.

OBJECT-TYPE

Is this LSP being purged by this system?

OBJECT-TYPE

The 16-bit Fletcher Checksum for this LSP.

OBJECT-TYPE

The remaining lifetime, in seconds, for this LSP.

OBJECT-TYPE

The length of this LSP.

OBJECT-TYPE

Flags carried by the LSP.

OBJECT-TYPE

The table of LSPs in the database.

OBJECT-TYPE

Each entry describes a TLV within an LSP currently stored in the system. Dynamically learned rows will not survive an agent reboot.

OBJECT-TYPE

The index of this TLV in the LSP. The first TLV has index 1, and the Nth TLV has an index of N.

OBJECT-TYPE

The sequence number for this LSP.

OBJECT-TYPE

The 16-bit Fletcher Checksum for this LSP.

OBJECT-TYPE

The type of this TLV.

OBJECT-TYPE

The length of this TLV.

OBJECT-TYPE

The value of this TLV.

OBJECT-IDENTITY

OBJECT-TYPE

The system level for this notification.

OBJECT-TYPE

The identifier of this circuit relevant to this notification.

OBJECT-TYPE

An Octet String that uniquely identifies a Link State PDU.

OBJECT-TYPE

Holds up to 64 initial bytes of a PDU that triggered the notification.

OBJECT-TYPE

Holds the System ID length reported in PDU we received.

OBJECT-TYPE

Holds the Max Area Addresses reported in a PDU we received.

OBJECT-TYPE

Holds the Protocol version reported in PDU we received.

OBJECT-TYPE

Holds the size of LSP we received that is too big to forward.

OBJECT-TYPE

Holds the size of isisSysLevelOrigLSPBuffSize advertised by the peer in the originatingLSPBufferSize TLV. If the peer does not advertise this TLV, this value is set to 0.

OBJECT-TYPE

Holds the size of LSP received from peer.

OBJECT-TYPE

The list of protocols supported by an adjacent system. This may be empty.

OBJECT-TYPE

The current state of an adjacency.

OBJECT-TYPE

An offset to a problem in a PDU. If the problem is a malformed TLV, this points to the beginning of the TLV. If the problem is in the header, this points to the byte that is suspicious.

OBJECT-TYPE

The type for a malformed TLV.

OBJECT-TYPE

An Area Address.
