1. Method for electing a master routing node of a given subnet of a network, which given subnet comprises nodes connected together by a same type of interface, wherein the nodes comprising at least two activated interfaces enabling a connection with the given subnet and another different subnet of the network are defined as router nodes, one of the nodes of the network being chosen as target node, said method comprising following steps:

  • determining a first-type address associated with the interface of each node on the given subnet, said first-type address being the address given by a routing table of the next hop on the path leading from said node to the target node, the next hop being a router node or said target node;

    determining a second-type address associated with the interface of each node on the given subnet, said second-type address being the determined first-type address if the determined first-type address is on said given subnet, or the address of the interface of said node on the given subnet if the determined first-type address is on another subnet of the network than said given subnet;

    sending by each router node of the given subnet a message containing its determined second-type address;

    collecting at the interface of each node on the given subnet said sent messages containing a second-type address associated with a router node of said given subnet;

    selecting for the interface of each node on the given subnet a third-type address among its determined second-type address (@RA) and the second-type addresses contained in the collected messages, according to a selection rule known by all nodes of said subnet;

    electing as master routing node of said given subnet the node having the selected third-type address.
