Abstract
A method of cyber-attack protection is provided. The method includes receiving a unicast packet at a first router and determining whether a destination for the unicast packet is behind a cooperating router. If the destination for the unicast packet is behind a cooperating router, the unicast packet is tunneled from the first router to a tunnel multicast address to which the cooperating router subscribes.
