ATM BRIDGE APPARATUS, AND LOOP DETECTING METHOD IN ATM BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide an ATM bridge apparatus capable of preventing occurrence of a loop at a plurality of points at the same time by loop setting of a plurality of interfaces for the maintenance of an ATM apparatus.

SOLUTION: The ATM bridge apparatus 1 interconnecting an ATM network 2 and a layer 2 network 3 is provided with: a MAC address learning function for a packet transmitted from its own apparatus; and a filtering function that monitors the MAC address of the packet received from the ATM network and discriminates the presence of a loopback packet when receiving the packet outputted from its own apparatus to abort the packet and inform a host about it.
