A communication network with controlled routing operations, including a set of nodes, wherein topological information on the network is broadcast to all the nodes in the set. The network is associated with an external network, such as, a standard public network, and certain nodes are configured to perform a gateway function between the network and the associated external network. Each node is configured for building two sets of addresses including one primary address, which is fixed and independent from the prefixes announced by the gateways and one or more secondary addresses which are valid global IP addresses, based on the global prefixes announced by the gateways. Each node in the network is configured for using one of the secondary addresses as the source address of outgoing traffic, and for generating and broadcasting multiple interface messages containing all its secondary addresses in the place of interface addresses.
