ABSTRACT:
A method and apparatus for providing link state routing protocol redundancy in a router. A router includes an active controller and at least one standby controller. An internal adjacency relationship is established between the active controller and the standby controller to enable automatic switchover upon disablement of said active controller. The adjacency relationship is established by mirroring configuration data on a standby controller from an active controller, synchronizing Hello information between the active and standby controllers, and synchronizing database information between the active and standby controllers.
