<p>The network apparatus (a switch (10)) of communication system ( fig.1 ), which has a path table (17) for registering a MAC address of a facing device (11) and a lending MAC address set in advance so as to be correlated with each other, and which has a MAC table (16) for registering the MAC address inherent to the device connected to the apparatus itself (10), and path identification information for specifying a combination between a MAC address of the facing device in the path table and the lending MAC address so as to be correlated with each other. The device also generates path identification information and registers the same at the path table when communicating through a pseudo wire, and resets the pseudo wire based on the path table and the MAC table when a device in communication is changed.</p> |
