Traps on OSPF state changes
RFC 1850,
OSPF Version 2 Management Information Base
, defines a portion of the
Management Information Base (MIB) for managing Version 2 of the Open
Shortest Path First Routing Protocol.
Objects defined in this MIB reside in the mib(1) subtree and have the object
identifier prefix ospf ({ mib-2 14 }).
This software version implements the following traps from the ospfTrap(16)
ospfTraps(2) subtree of the OSPF Version 2 MIB:
■
The ospfIfStateChange trap ({ ospfTraps 16 }) is generated when a
non-virtual OSPF interface changes state, and contains the following
objects:
•
ospfRouterId, the router ID of the originator of the trap
•
ospfIfIpAddress, the IP address of the interface that changed state, for
interfaces with an IP address
•
ospfAddressLessIf, the ifIndex of the interface that changed state, for
addressless interfaces
•
ospfIfState, the new state of the interface
■
The ospfVirtIfStateChange trap ({ ospfTraps 1 }) is generated when a
virtual OSPF interface changes state, and contains the following objects:
•
ospfRouterId, the router ID of the originator of the trap
•
ospfVirtIfAreaId, the transit area used by the virtual interface
•
ospfVirtIfNeighbor, the router ID of the virtual neighbour
•
ospfVirtIfState, the new state of the virtual interface
■
The ospfNbrStateChange trap ({ ospfTraps 2 }) is generated when a
non-virtual OSPF neighbour changes state, and contains the following
objects:
•
ospfRouterId, the router ID of the originator of the trap
•
ospfNbrIpAddr, the IP address the neighbour uses as its IP source
address
