  • Method and system for implementing IS-IS protocol redundancy
    Patent number: 7155632
    Abstract: The present invention relates to a method and system for implementing link level protocol redundancy in a router. In particular, the invention relates to providing redundancy of the Intermediate System Intra-domain Routing Information Exchange Protocol (IS-IS) routing protocol. An active processor provides IS-IS operations. In the present invention, a standby processor is coupled to the active processor. During the initial synchronization, all protocol information from the active processor is forwarded to the standby processor. The protocol information can include IS-IS global protocol information, IS-IS configuration information, IS-IS adjacencies information, IS-IS interface information and link state packet information. Thereafter, any updates of protocol information are immediately forwarded to the standby processor in an orderly and controlled manner.
