ABSTRACT:
A method for reconfiguring a packet-switched communication network using a network protocol for installing a logic topology of the network formed as a spanning tree is disclosed. The method includes detecting failure of a direct link to a root bridge of the spanning tree by a first bridge; detecting the failure of a direct link to the root bridge by a second bridge; transmitting a first configuration frame generated by the first bridge to other bridges; receiving the first configuration frame by a third bridge and transmitting a second configuration frame, generated by the third bridge, to the other bridges; detecting the first or second configuration frame by the second bridge and transmitting the third configuration frame generated by the second bridge to the other bridges; receiving the third configuration frame by the other bridges of the network and triggering a reconfiguration of the network with detection of a new spanning tree by the network protocol.
