Abstract
A method and apparatus for quickly determining the status of a network device in a network communicates status inquiry messages over the forwarding plane of one network device to at least one neighboring network device. The status inquiry messages indicate the connectivity status with at least one neighboring device. The status inquiry messages are transmitted periodically to the at least one neighboring device. In addition, the network device may communicate an advertisement message over the control plane to discover the at least one neighboring network device prior to the communication of the status inquiry messages over the forwarding plane. The network devices may negotiate communication parameters for the exchange of status inquiry messages with the at least one network device.
