<p><P>PROBLEM TO BE SOLVED: To ensure the setting of the LAN or WAN of each external network device connection part IF. <P>SOLUTION: The router includes an interface connector IF, a switching hub part IF connected to it, a control part and a changeover switch part. The switching hub part comprises a physical processing part PHY, a logical processing part MAC of the high order, and a line concentration part for concentrating the high order side input/output ports of the MAC. The MAC(X) and a controller are connected by MII0, and the PHY(Y) and the controller are connected by MII1. The controller sets the IF to be connected to the PHY(Y) to the WAN by invalidating the MAC(Y) and validating the MII1 while performing routing. The controller sets the IF to be connected the PHY(Y) to the LAN by validating the MAC(Y) and invalidating the MII0. They are specified by a user in the changeover switch part. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
