During the initial full discovery, the Topology Split Manager populates its repository with the devices and network connections that it discovers in the managed IP network domain. During any subsequent full discovery, the Topology Split Manager rediscovers the devices and network connections in the managed IP network domain.

The discovery flow up to postprocessing is essentially the same as for any IP Manager except that the discovery is more streamlined. During the postprocessing phase of discovery, and only if the NumberOfDomains configuration parameter is set, the Topology Split Manager starts a topology-split driver that invokes topology split.

Chapter 2, Configuring the Topology Split Manager, identifies the discovery configuration tasks in a Topology Split Manager deployment and provides the procedures for completing those tasks. Chapter 3, Initiating Discovery and Topology Split, presents procedures for initiating discovery in a Topology Split Manager deployment.
