Abstract
A control plane redundancy system includes a control system that is configured to provide a plurality of control plane functionalities to a network, a primary networking device that is configured to establish a first communication connection with the control system, and a secondary networking device that is configured to establish a second communication connection with the primary networking device and a third communication connection with the control system. The primary networking device can transmit to the control system a secondary networking device identifier that identifies the secondary networking device as a redundant networking device for the primary networking device when the first communication connection is unavailable. The secondary networking device can determine that the primary networking device is still active when the first communication connection is unavailable and, in response, establish a proxy communication connection between the primary networking device and the control system.
