Abstract
Systems and methods for redundancy in a network device are disclosed. An exemplary network device comprises: a plurality of data forwarding elements (DFEs); and a redundant control plane. The redundant control plane comprises: an active control processor for configuring forwarding operation of each of the DFEs; an active layer-2 switch coupled to the active control processor and to each of the DFEs; a standby control processor; and a standby layer-2 switch coupled to the standby control processor and to each of the DFEs. The active control processor is programmed in a full-mesh so that the active control processor is in communication with each of the DFEs. The standby control processor is programmed in a full-mesh so that the standby control processor is in communication with each of the DFEs.
