VMware Smart Assurance discovery is the process of using VMware Smart Assurance object class models to create a representation of the managed topology within the repository, or database, of a Domain Manager. For MPLS Manager, data is collected from MPLS-enabled devices in the managed network to create instances of MPLS and VPN topology objects, their relationships, and their logical connections.

When an MPLS-enabled device is added to the managed network, MPLS Manager performs discovery on the device to determine the MPLS and VPN topology objects that are associated with the device. When an MPLS-enabled device is removed from the managed network and deleted from the topology, MPLS Manager removes the device and all the device’s associated MPLS and VPN topology objects from the modeled topology.
