Abstract
The present disclosure relates to systems, methods, and non-transitory computer readable storage medium for detecting a tunnel routing loop attack on a computer network. A method of the presently claimed invention receives a packet of data over an automatic tunnel. When the received packet includes an Internet protocol version 6 (IPv6) packet headers in the received packet may be extracted from the received packet. When an extracted header is a tunnel routing loop attack (TRLA) header, address information included in the TRLA header may be matched to a destination address that the IPv6 packet is about to be tunneled through. When the address information included in the TRLA header matches the destination address that the IPv6 packet is about to be tunneled through the IPv6 packet is dropped because the match indicates that that a loop is about to be formed.
