When discovery occurs

initiates a discovery cycle of the routing topology objects whenever:
  • IP Availability Manager
    is added as a source to
    , as explained in Chapter 4, “Preparing and Initiating Discovery.”
  • IP Availability Manager
    completes a discovery cycle.
    By default, each time
    IP Availability Manager
    completes a discovery cycle,
    performs a topology synchronization to import device topology information from
    IP Availability Manager
    . It then performs its own discovery by sending SNMP requests or CLI commands to the devices to discover or rediscover routing topology objects.
  • is restarted or communication is lost and then reestablished between
    and
    IP Availability Manager
    .
