SYNCHRONIZING FORWARDING DATABASES IN A NETWORK DEVICE BACKGROUND

摘要

Synchronizing forwarding databases in a network device. A first forwarding database may be maintained in a database engine portion of the network device. The forwarding database may include a plurality of entries, each of the entries comprises a synchronization field. The forwarding database may also include a global synchronization value used for the synchronization. A controller in the network device may receive a message indicating one or more changes to a first one or more entries in the forwarding database. The first one or more entries have a first global synchronization value in the synchronization field. Accordingly, the global synchronization value may be changed to a second value and a query may be performed using the first global synchronization value to return changes to the first entries. Changes to other entries in the forwarding database that occur after the global synchronization value is changed may not be part of the query results.
