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
