Abstract

The invention relates to transmitting datagrams according to a redundancy protocol, wherein the datagrams are originally transmitted according to a first redundancy protocol which is employed for redundantly transmitting the datagrams within a first network section (MRP1, MRP2, MRP3, MRP4, RSTP1, RSTP2). Between a first endpoint and a second endpoint, the datagrams are transmitted via a second network section (HSR1) in which a second redundancy protocol is employed, wherein the two endpoints interface the first network section and the second network section. Upon detecting a topology change in the first network section by a detecting network device (111), the detecting network device sends a topology change notification (TC) to other network devices in the first network section, the topology change notification causing network devices (111-112, 121-124, 131-132, 141-145, 151-153) in the first network section to update their respective source address table. Upon receiving the topology change notification at a first endpoint device (201-206, 209-210) comprising the first endpoint, the first endpoint device clears its source address table immediately or after waiting a predetermined first duration and starts learning source addresses of other network devices. Upon receiving the topology change notification at a second endpoint device comprising the second endpoint, the second endpoint device waits a predetermined second duration before clearing its source address table and starting to learn source addresses of other network devices, the second duration being longer than the first duration.
