NetEngine IAD User Guide
This chapter describes how to configure the IAD as a bridge. A bridge is a
device that connects and passes packets between two network segments
that use the same communications protocol. A router generally improves
overall efficiency for a complex network, but a bridge provides better
speed and flexibility for the overall network.

Bridges operate at the data link layer (Layer 2) of the OSI reference model.
In general, a bridge filters, forwards or floods an incoming frame based on
the MAC address of that frame.

NOTE
Verilink recommends that bridged network architecture be
thoroughly understood prior to configuring the IAD.
