1. A non-transitory computer-readable medium configured for storing a program that is executable by a processing device in a node, the program enabling the processing device to:
receive a packet from a first peer device on a network,
determine whether a mismatch exists in an authentication of the packet from the first peer device, and
responsive to the authentication mismatch, send a flush instruction to a plurality of peer devices on the network to remove any link state packets from the first peer device at the plurality of peer devices by resetting a lifetime expiration of the link state packets from the first peer device to zero at the plurality of peer devices, and send blocking instructions to the plurality of peer devices to block future packets destined for the first peer device.
