SmartMIB Small Solution:

Higher Level OSPF Area Metrics

(SM-SmallSol018)

Solution’s SOSL Based management process script:

The solution defines the following main modules:

MainOspfMIBTables:

This is the main module that controls and instantiates the ‘OspfMibTables’ module.

MainOspfAreaLsaChecksum:

This is the main module that controls and instantiates the ‘OspfAreaLsaChecksum1’ and the ‘OspfAreaLsaChecksum2’ modules.

The details of the Main modules and the transient Service modules are provided below:
