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.

Packet fragmentation in GRE

Examples described herein relate to a selection of a network device in a network installation for a forwarder operation. Selection may include computing a performance score based on a set of performance parameters. Broadcasting the computed performance score to other network devices. Receiving performance scores from the other network devices. Comparing the received performance scores with the computed performance score. Continuing in the forwarder mode based on a determination that the received performance scores are less than its computed performance score. Receiving multicast Domain Name Service (mDNS) packets from one or more client devices. Sending the received mDNS packets to a central service.
