Periodic verification of manually provisioned IS-IS routing data

摘要

The present invention provides a network element of a first type for operating in a network including other network elements of such first type and for allowing the other network elements to form part of the network that are not of the first type. Each of the first type of network element has the ability to automatically determine the topology of the network for each network element of such first type and further has the ability to store manually provisioned routing information about the network elements not of the first type when the network elements not of the first type are in the path to a network element of the first type. Each network element of the first type further comprises a circuit for periodically checking the validity of manually provisioned routing information.
