Abstract:
1. A method of handling datagrams in a network device coupled to other network devices, the method comprising: performing, by the network device, a lookup of an address resolution lookup ARL table based on a source address contained in an incoming datagram to determine whether the source address has been learned previously; determining, when the source address has been learned previously, whether the other network devices have learned the source address by examining a learned all devices tag for the source address in the ARL table; and when it is determined that the other network devices have not learned the source address: sending, by the network device, a learning message with the source address to the other network devices; and re-sending, by the network device, the learning message to the other network devices until the learning message is returned to the network device from one of the other network devices.
