The present invention comprises a method and apparatus for managing nodes of a network. In one embodiment, the invention is implemented as part of a computer based network management system. The system allows a network operator to select, view and modify the configuration of a logical group node at any level of a network hierarchy. The configuration of a logical group node may include, without limitation, logical group node attributes, summary addresses, and any other information that may be relevant to implementing the desired function of a logical group node. After a change is made to the configuration of a logical group node, the system automatically identifies all physical nodes that may potentially function as the logical group node whose configuration has changed, and causes the configurations of the logical group node to be updated on the identified physical nodes to reflect the change made to the logical group node. In this manner, modifications made to a logical group node are automatically propagated to all physical nodes, at lower levels of hierarchy therein, that might run the logical group node function, eliminating the need to manually update each physical node's configuration one physical node at a time. The invention may be used with any network that involves the aggregation of physical nodes into a hierarchy of logical group nodes, including, without limitation, networks using the PNNI and IP protocols.
