Abstract
Implementations of the present disclosure relate to packet fragmentation in Generic Routing Encapsulation (GRE). A method comprises in accordance with a determination that the target packet is to be fragmented, generating at least two packets from the target packet. The at least two packets comprise an Internet Protocol (IP) header, a GRE header and a fragment of the payload of the target packet, respectively. The GRE header comprises a fragment indication indicating that the respective packet comprises a respective fragment of the payload of the target packet. The method further comprises transmitting the at least two packets to a second network device. In this way, the packet fragment dropping due to security policies will be avoided.
