Overview
A bridge connects two or more LANs together at Layer 2 (data link) of
the ISO-OSI 7 layer model. A learning bridge links networks, but also
separates network traffic and forwards only the packets that need to be
forwarded based on Media Access Control (MAC) address.
the ISO-OSI 7 layer model. A learning bridge links networks, but also
separates network traffic and forwards only the packets that need to be
forwarded based on Media Access Control (MAC) address.
The OfficeConnect Remote 840 can be configured as a learning bridge.
Bridges separate traffic by examining the MAC addresses contained in
data packets. MAC addresses uniquely identify each machine attached to
a network segment. A data packet is not forwarded to another segment
if its destination MAC address resides on the same segment as its source.
