Abstract
There is provided a method for electing a master routing node of a given subnet of a network, comprising: determining () a first-type address associated with an interface of each node on the given subnet, and being the address given by a routing table of the next hop (router node or target node) on the path leading from the node to a target node; determining () a second-type address associated with the interface of each node on the given subnet, and being either the determined first-type address (if the latter is on the given subnet) or the address of the interface of the node on the given subnet (if the determined first-type address is on another 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 the sent messages; selecting () for the interface of each node on the given subnet a third-type address among its determined second-type address and the second-type addresses contained in the collected messages, according to a selection rule known by all nodes of the subnet; electing () as master routing node of the given subnet the node having the selected third-type address.
