The MPLS Topology Server performs the following steps to discover MPLS topology:

  1. Imports initial topology and CLI device-access objects from IP Availability Manager and adds the data to its repository.

  2. Probes the imported MPLS-relevant router and switch devices for MPLS topology information (such as LSP hops) and creates MPLS objects and their relationships in its repository.

  3. Combines the information that is collected from the various probes to create additional MPLS objects and relationships.

  4. Exports the device and MPLS topology to the Global Manager.

  5. Exports a subset of the device and MPLS topology to the MPLS Monitoring Server and the MPLS Analysis Server.
