A router made up firstly of at least two router modules, only one of which is in an active state at any given time, the others being in a standby state, and secondly of changeover means making it possible to cause one of the other router modules to go from a standby state to an active state when the router module in the active state stops, each of the router modules having connections with one or more networks, and having at least one state machine, each state machine managing the interface associated with one of the connections. In the router, each of the router modules has data storage means which, in the active state, enable it to store data relating to the state of said at least one state machine, when said machine is in a stable state, and data retrieval means for retrieving said data when a changeover takes place.
