A group-learning method for a network (1) that has a tree topology and includes a plurality of nodes (2), each node being provided with a network address, being connected to other nodes by means of a plurality of ports (p1-p7), and implementing a data structure containing a plurality of addresses of nodes, each associated to a corresponding port (P out ) of the node, the plurality of ports including at least one root port and one reception port. The method includes the steps of: a) for each node that changes root port by replacing an old root port with a new root port, sending through the new root port a current updating message, containing a set of addresses of nodes; b) for each node that receives the current updating message from a respective reception port (P out ), storing the current updating message and the reception port for a storage time (T m ); verifying the presence in memory of possible previous updating messages; and updating the data structure on the basis of the set of addresses of nodes, of the reception port, and of the possible presence in memory.
