9. A method to update network address information in a communication system using a bridge, the method comprising:
-
if a bridge device is replaced, obtaining an internet protocol (IP) address by the replaced bridge device; transmitting, by the replaced bridge device, a packet indicating the replacement of the bridge device to an internal network node; and broadcasting, by the replaced bridge device, a message to update the network address information to an external network node, wherein table information including the network address information is updated in the external network node that has received the message. - View Dependent Claims (10, 11, 12, 13, 14)

15. A bridge device in a communication system that uses a wired or wireless bridge, the bridge device comprising:
-
a first network interface configured to communicate with an external network; a second network interface configured to communicate with an internal network; and a medium access control (MAC) layer interface configured to; control a bridge function to obtain an internet protocol (IP) address if a bridge is changed, transmit a packet indicating the change in bridge to a node of the internal network through the second network interface, and broadcast a message to update the network address information to an external network node through the first network interface, wherein table information including the network address information is updated in the external network node that has received the message. - View Dependent Claims (16, 17, 18, 19, 20)
