Method and system for communication

Method for auto-configuration of a router, the router being a part of an IP intranetwork, the IP intranetwork comprising routers interconnected via Point to Point links, said method comprising the steps of:

• establishing a physical connection between the router and an existing router within the intranetwork;
• establishing a Point to Point link between the router and the existing router, over the physical connection;
• requesting and retrieving an IP address to make IP communication possible between the router and the existing router over the Point to Point link;
• automatically identifying the resources which are essential for retrieving configuration information for the router;
• automatically configuring the router by means of the configuration information;
• and
• starting a routing protocol to establish network connectivity between the router and the rest of the intranetwork;
• wherein a set of additional routers to be autoconfigured is added to said router, in cascade, wherein the first of said additional routers, connected to said router, is autoconfigured according to the prior steps, and then comprising the further steps of:
• starting the autoconfiguring of one of said additional routers closest connected to the last configured router;
• and
• repeating the former step until all of said additional routers in the set are autoconfigured.
