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.

Claim (Index 1):
A method for detecting a tunnel routing loop attack on a computer network, the method comprising:\n receiving an internet protocol version 6 (IPv6) packet at a first network device over a network interface; adding address information to the IPv6 packet that identifies a second network device in a tunnel routing attack (TRLA) header; encapsulating the IPv6 packet in an IPv4 packet; forwarding the IPv4 packet to a second network device through an automatic tunnel to the second network device; receiving a second version of the IPv6 packet at the first network device; identifying that the IPv6 packet includes the TRLA header; identifying that that the first network device that has previously forwarded the IPv6 packet from the address information in the TRLA header; and dropping the packet after identifying that the first network device previously forwarded the IPv6 packet to the second network device.
