DECAPSULATION OF DATA PACKET TUNNELS TO PROCESS ENCAPSULATED IPV4 OR IPV6 PACKETS

摘要

In one embodiment, a non-transitory processor-readable medium stores code representing instructions to cause a processor to determine whether an IPv4 payload of an IPv4 packet includes a tunneled IPv6 packet. When the IPv4 payload includes the tunneled IPv6 packet, the code can determine a location of a payload of the tunneled IPv6 packet based at least in part on a header of the tunneled IPv6 packet, and send a signal to block transmission of the IPv4 packet when the payload of the tunneled IPv6 packet is not a valid IPv6 payload.
