Automatic full discovery reveals any changes in the configuration or connectivity of the routing-protocol system and keeps the topology current.

The parameters that control automatic full discovery are located on the Topology tab of the Domain Manager Administration Console. By default, automatic full discovery is disabled for Network Protocol Manager.

Automatic full discovery should be enabled and scheduled for the one or more IP Availability Manager sources, not for Network Protocol Manager. That way, whenever an IP Availability Manager source performs an automatic full discovery, Network Protocol Manager performs an automatic full discovery.

Also, when you configure automatic full discovery, say weekly or daily, you should schedule the full discovery during off hours (5 A.M., for example). Running the discovery more often will provide a more accurate routing topology but will also cost more in terms of network and system resources.

The VMware Smart Assurance IP Manager documentation provides instructions for enabling and scheduling automatic full discovery for IP Availability Manager.
