Abstract
A network device may receive, from a first network, a network packet of a first network packet type that encapsulates a fragment of a second network packet of a second network packet type, where the network packet includes an extension header that indicates a source port and a destination port for the second network packet. The network device may perform an anti-spoof check on the fragment of the second network packet based at least in part on at least one of: the source port or the destination port for the second network packet that is indicated by the extension header. The network device may, based on the fragment passing the anti-spoof check, forward the fragment of the second network packet to a second network.
