OLSRv2-MIB

TEXTUAL-CONVENTION

OLSRv2 Metrics are expressed in terms of a Link Metric Compressed Form within the OLSRv2 protocol. This textual convention defines the syntax of the metric objects consistent with the definitions of the OLSRv2 Link Metric Compressed Form in Section 6.2 of RFC 7181. The 12-bit compressed form of a link metric uses a modified form of a representation with an 8-bit mantissa (denoted a) and a 4-bit exponent (denoted b). Note that if represented as the 12-bit value 256b+a, then the ordering of those 12-bit values is identical to the ordering of the represented values. The value so represented is (257+a)2^b - 256, where ^ denotes exponentiation. This has a minimum value (when a = 0 and b = 0) of MINIMUM_METRIC = 1 and a maximum value (when a = 255 and b = 15) of MAXIMUM_METRIC = 2^24 - 256. Hence, the metric values so represented range from 1 to 16776960. The special value of 0 is reserved for the UNKNOWN_METRIC value. If a network manager sets the metric value 'm' through the MIB module, then the OLSRv2 code can both use this value and derive a compressed representation of 'm' (as used in messages) as specified in Section 6.2 of RFC7181. The value 'm' is persistently stored by the MIB module. If the MIB module is pulling this metric's value from some other source, e.g., the protocol instance, then this value is stored as is.

TEXTUAL-CONVENTION

Controls the operation of the OLSRv2 protocol on the device or a specific interface. For example, for an interface, 'enabled' indicates that OLSRv2 is permitted to operate, and 'disabled' indicates that it is not.

TEXTUAL-CONVENTION

OLSRv2 time values may be expressed in terms of a compressed form within the OLSRv2 protocol. This textual convention defines the syntax of the time objects defined in terms of an integer number of milliseconds, consistent with the definitions of the 8-bit exponent-mantissa compressed form defined in Section 5 of RFC 5497. Time values with this representation are defined in terms of a constant C, which is represented in terms of seconds. The constant C (time granularity) is used as specified in RFC 5497. It MUST be the same as is used by NHDP (RFC 6130). The 8-bit compressed form of a time value uses a modified form of a representation with a 3-bit mantissa (denoted a) and a 5-bit exponent (denoted b). Note that if represented as the 8-bit value 8b+a, then the ordering of those 8-bit values is identical to the ordering of the represented values. The minimum time value that can be represented in this manner is C. The maximum time value that can be represented in this manner is 15 * 2^28 * C, 15*268,435,456 * C, 4,026,531,840 * C, or about 45 days if, for example, C = 1/1024 second. This TEXTUAL-CONVENTION limits the maximum value of the time granularity constant C to be no greater than 1/1024 seconds due to its use of the Unsigned32 syntax limiting the maximum number of milliseconds to no more than 3932160000. When OLSRv2 uses this 8-bit exponent-mantissa compressed form, this object value MUST be translated from the integer form represented in this MIB module into the exponent-mantissa form for the OLSRv2 protocol to use according to the algorithm defined in Section 5 of RFC 5497 for finding the next larger time value within the exponent-mantissa format. If a network manager sets the time value 't' through the MIB module, then the OLSRv2 code can derive 'compressed_t' = T(a,b) according to the algorithm in RFC 5497 and 'compressed_t' is the value represented in the OLSRv2 messages. But, the value 't' is persistently stored by the MIB module. If the MIB module is pulling this time parameter from some other source that is using the compressed form, i.e., the protocol instance, then this value is stored as is, after converting from number of time constants C into number of milliseconds.

TEXTUAL-CONVENTION

A willingness value that evaluates to the device's interest in participating in a particular function, process, or behavior. The willingness ranges from a low value of WILL_NEVER(0) to a high value of WILL_ALWAYS(15). For each parameter x, there is an associated willingness value W(x) such that WILL_NEVER < W(x) <= WILL_ALWAYS.

It is RECOMMENDED that the value of this threshold be set to at least 20 and higher in dense topologies with frequent expected topology changes.

OBJECT-TYPE

This object is used to determine whether to generate an olsrv2RoutingSetRecalculationCountChange notification. This object represents an interval from the present moment, extending into the past, expressed in hundredths of a second.

OBJECT-TYPE

The configured status of the OLSRv2 process on this device. 'enabled(1)' means that OLSRv2 is configured to run on this device. 'disabled(2)' mean that the OLSRv2 process is configured off. Operation of the OLSRv2 protocol requires the operation of the Neighborhood Discovery Protocol (RFC 6130). Hence, this object cannot have a status of 'enabled' unless at least one interface on the device is a MANET interface with NHDP enabled on that interface. If a network manager attempts to set this object to 'enabled' when no interfaces on this device have NHDP enabled, the device MUST fail the set with inconsistentValue. If all device interfaces running NHDP become disabled or removed, then the olsrv2AdminStatus MUST be 'disabled'. If the network manager, or other means, sets this object to 'disabled', then the associated interface specific objects, i.e., the olsrv2InterfaceAdminStatus objects MUST all be 'disabled'. This object is persistent, and when written, the entity SHOULD save the change to non-volatile storage.

OBJECT-TYPE

The olsrv2InterfaceTable describes the OLSRv2 status on the NHDP interfaces of this router. As such, this table augments the nhdpInterfaceTable defined in the NHDP-MIB (RFC 6779). NHDP interfaces are explicitly defined by network management, command line interface (CLI) or other means for interfaces on the device that are intended to run MANET protocols. The olsrv2InterfaceTable contains a single object: the olsrv2InterfaceAdminStatus object. This object is set by network management, or by other means, e.g., CLI. A conceptual row in this table exists if and only if a corresponding entry in the nhdpInterfaceTable exists. If the corresponding entry with nhdpIfIndex value is deleted from the nhdpInterfaceTable, then the entry in this table is automatically deleted and OLSRv2 is disabled on this interface, and all configuration and state information related to this interface is to be removed from memory. The olsrv2InterfaceAdminStatus can only be 'enabled' if the corresponding olsrv2AdminStatus object is also set to 'enabled'.

OBJECT-TYPE

The olsrv2InterfaceEntry describes one OLSRv2 local interface configuration as indexed by its nhdpIfIndex, as defined in the NHDP-MIB (RFC 6779). The objects in this table are persistent, and when written, the device SHOULD save the change to non-volatile storage. For further information on the storage behavior for these objects, refer to the description for the nhdpIfRowStatus object in the NHDP-MIB (RFC6779).

OBJECT-TYPE

The value 'disabled(2)' denotes that the interface is not permitted to participate in the OLSRv2 routing process. The configuration objects for the OLSRv2 routing process, other than the administrative status objects, are common to all interfaces on this device. As such, the OLSRv2 configuration objects are globally defined for the device and are not contained within the olsrv2InterfaceTable.

Specific instructions for the olsrv2TibAdRemoteRouterSetEntry(s) are found in Section 10.1 and Section 17 of OLSRv2 (RFC 7181).

OBJECT-TYPE

The type of the olsrv2TibAdRemoteRouterSetIpAddr, as defined in the InetAddress MIB module (RFC4001). Only the values 'ipv4(1)' and 'ipv6(2)' are supported.

OBJECT-TYPE

This is the originator address of a received TC message.

OBJECT-TYPE

This is the greatest Advertised Neighbor Sequence Number (ANSN) in any TC message received that originated from the router with originator address olsrv2TibAdRemoteRouterSetIpAddr. Sequence numbers are used in the OLSRv2 protocol for the purpose of discarding 'old' information, i.e., messages received out of order. However, with a limited number of bits for representing sequence numbers, wraparound (that the sequence number is incremented from the maximum possible value to zero) will occur. To prevent this from interfering with the operation of this protocol, OLSRv2 implementations observe the following when determining the ordering of sequence numbers. In OLSRv2, MAXVALUE designates one more than the largest possible value for a sequence number. For a 16-bit sequence number, MAXVALUE is 65536. The sequence number S1 is said to be 'greater than' the sequence number S2 if: o S1 > S2 AND S1 - S2 < MAXVALUE/2 OR o S2 > S1 AND S2 - S1 > MAXVALUE/2 When sequence numbers S1 and S2 differ by MAXVALUE/2, their ordering cannot be determined. In this case, which should not occur, either ordering may be assumed. Thus, when comparing two messages, it is possible - even in the presence of wraparound - to determine which message contains the most recent information.

OBJECT-TYPE

The type of the olsrv2TibRouterTopologySetToOrigIpAddr, as defined in the InetAddress MIB module (RFC4001). Only the values 'ipv4(1)' and 'ipv6(2)' are supported.

OBJECT-TYPE

This is the originator address of a router that can be reached by the router with originator address TR_to_orig_addr in one hop.

OBJECT-TYPE

This is the greatest Advertised Neighbor Sequence Number (ANSN) in any TC message received that originated from the router with originator address TR_from_orig_addr, i.e., that contributed to the information contained in this Tuple and that is defined by the objects: (olsrv2TibRouterTopologySetFromOrigIpAddrType, olsrv2TibRouterTopologySetFromOrigIpAddr). Sequence numbers are used in the OLSRv2 protocol for the purpose of discarding 'old' information, i.e., messages received out of order. However, with a limited number of bits for representing sequence numbers, wraparound (that the sequence number is incremented from the maximum possible value to zero) will occur. To prevent this from interfering with the operation of this protocol, OLSRv2 implementations observe the following when determining the ordering of sequence numbers. In OLSRv2, MAXVALUE designates one more than the largest possible value for a sequence number. For a 16-bit sequence number, MAXVALUE is 65536. The sequence number S1 is said to be 'greater than' the sequence number S2 if: o S1 > S2 AND S1 - S2 < MAXVALUE/2 OR o S2 > S1 AND S2 - S1 > MAXVALUE/2 When sequence numbers S1 and S2 differ by MAXVALUE/2, their ordering cannot be determined. In this case, which should not occur, either ordering may be assumed. Thus, when comparing two messages, it is possible - even in the presence of wraparound - to determine which message contains the most recent information.

OBJECT-TYPE

This is the neighbor metric from the router with originator address TR_from_orig_addr (olsrv2TibRouterTopologySetFromOrigIpAddrType, olsrv2TibRouterTopologySetFromOrigIpAddr) to the router with originator address TR_to_orig_addr (olsrv2TibRouterTopologySetToOrigIpAddrType, olsrv2TibRouterTopologySetToOrigIpAddr).
