Abstract
Approaches for determining the actual physical topology of network devices in a network are disclosed. To determine a physical topology, a discovery mechanism determines a set of network addresses for identifying devices within a network. Based on the set of network addresses, the discovery mechanism identifies a group of devices that are associated with the network. Layer 2 and Layer 3 configuration information is gathered from the group of devices to identify possible neighboring devices within the network. The configuration information is then processed to generate topology information that identifies true neighboring devices and the actual links that exist between each of the neighboring devices. The approaches eliminate misleading information and prevent generation of incorrect topologies.
