By default, the MPLS servers connect to the configured underlying IP Managers to fetch initial topology for MPLS discovery. This functionality needs to be disabled on both the Active and Standby MPLS Managers in a failover deployment before starting them.

The Failover Manager determines the MPLS component where the topology synchronization and discovery is enabled. Discovery or topology synchronization is always enabled on the Active MPLS Managers and disabled on the Standby MPLS Managers.

For both Active and Standby locations, use the following steps to disable discovery or topology synchronization for all three MPLS servers.

  1. In the installation area where MPLS is running, go to the BASEDIR/smarts/bin directory and open the bootend.conf file for MPLS Topology Server. Type:

    ./sm_edit conf/mpls-t/bootend.conf
  2. Navigate to the following section in the bootend.conf file and change the value of suspendTopologyManager from False to TRUE.

    ICF_TopologyManager::ICF-TopologyManager {
    # suspendTopologyManager
    # Suspends all topology manager operations
    # Set this to TRUE if you are using the MPLS Topology Server
    # in a failover configuration
    # Default value is FALSE
        suspendTopologyManager = TRUE
  3. Save the file and exit.

  4. Repeat Steps 1-3 for the MPLS Monitoring Server. Change the value of suspendTopologyManager in the mpls-m/bootend.conf file.

  5. Repeat Steps 1-3 for the MPLS Analysis Server. Change the value of suspendTopologyManager in the mpls-a/bootend.conf file.
