A device may include a control module and a line card. The control module may be configured to run a routing protocol to obtain routing information from network devices. The line card may include a processor. The processor may be configured to establish a bidirectional forwarding detection (BFD) session with a remote device, determine whether an interface associated with the BFD session is flapping, terminate the BFD session when the interface is flapping, disable the interface when the interface is flapping, re-enable the interface after a dampening recovery period elapses, reestablish the BFD session, and send a BFD packet to the remote device.
