The topology synchronization program probes for topology immediately after an IP Availability Manager is added as a topology source, and then every time thereafter whenever:

  • The IP Availability Manager completes a discovery cycle.


    Assumes StopAutoAMSync parameter in mpls.conf file is FALSE (default).

  • The connection to IP Availability Manager is lost and then reestablished.

    Each time that an IP Availability Manager completes a discovery cycle, the MPLS Topology Server performs the following incremental discovery:

  • Compares the current IP Availability Manager topology with the previously imported topology.

  • Conducts discovery only on new devices, or on known devices that have a newer discovery timestamp.

    For additional information about MPLS topology synchronization, see “When discovery occurs” on page 33 and “How discovery is conducted” on page 34.
