Abstract
A networking device such as a router may include, in one embodiment, a database storing a plurality of link state entries, and a cache operatively coupled with the database, the cache storing entries relating to the link state entries of the database. The networking device may also include a module for sending, over a network, packets including link state data, the module operatively coupled with the cache. In one example, the module accesses the cache to create one or more packets including link state data. Embodiments of the invention may be used for forming CSNP packets (complete sequence number packets) without the need for having to repeatedly walking a link state database in order to form the CNSP packets.
