The flow of data across IP networks depends upon both the physical connectivity among the network devices and the routing protocols that run on those devices. The routing protocols dictate the paths across which packets flow within and between the independent networks, or autonomous systems.

Network Protocol Manager for OSPF diagnoses connectivity failures for an interior gateway protocol known as Open Shortest Path First. Network Protocol Manager for OSPF, working with VMware Smart Assurance IP Availability Manager, discovers and monitors network devices that are running OSPF services, diagnoses OSPF-related failures, and exports the results of its analysis to the VMware Smart Assurance Service Assurance Manager (Global Manager). Network Protocol Manager for OSPF also detects common configuration problems that occur when deploying and maintaining the routing infrastructure.

The challenge of managing routing-protocol connectivity is that of determining which routing-protocol alarms are root-cause problems and which are symptoms of root-cause problems.

Network Protocol Manager for OSPF meets this challenge by:

  • Correlating and analyzing the alarms generated as a result of a physical-transport or OSPF object failure.

  • Pinpointing the object failure.

  • Identifying all monitored objects affected by the failure.

    This functionality allows Network Protocol Manager for OSPF users to address the problem of the failed object promptly and to dismiss all other alarms as symptoms of the problem.
