The invention relates to a method for reconfiguring a packet-switched communication network comprising a first network using a first network protocol and a second network using a second network protocol different from the first network protocol, in which the two networks are interconnected by two redundant data links, of which only one is activated for the exchange of useful data. A first redundant data link is preset to be activated and a second redundant data link is preset to be deactivated. Said method is characterised by the following steps: a failure of the first redundant data link is detected by a first bridge of the second network, connected to the first redundant data link; a first data packet is generated by the first bridge of the second network and the first data packet is transmitted to a second bridge of the second network, connected to the redundant second data link; and the first data packet is received and processed by the second bridge of the second network. The first data packet contains logical information by which means the at least partial implementation of the first network protocol on a port of the second bridge connected to the redundant second data link,and an activation of the second redundant data link,are triggered by the first network protocol.
