ABSTRACT:
A local area network comprises a peripheral equipment effecting layer2switching and including physical link aggregation means, and first and second core equipments effecting layer2switching and including physical link aggregation means. The peripheral equipment is connected to the first and second core equipments by first and second physical links, and the first and second core equipments are connected to each other by a third physical link. The first and second core equipments also respectively comprise first and second management means each adapted to detect the presence of the core equipment in which they are not installed via the third physical link coupling them and in the event of mutual detection to instruct the transmission of a common identifier to the peripheral equipment so that it considers the first and second core equipments as a single layer2switch and its aggregation means aggregate the first and second physical links with the aggregation means of the first and second core equipments.
