RFC 1483 Bridged

When you use RFC 1483 style bridging, Ethernet frames are bridged over ATM Virtual Circuits.
The Ethernet frames are encapsulated using either LLC Encapsulation or VC Multiplexing. With
LLC encapsulation, a link control header is added to the Ethernet packet that identifies the
protocol type (Ethernet). This allows multiple protocols to be transmitted over the ATM Virtual
Circuit. With VC Multiplexing, no link control header is needed as the ATM Virtual Circuit is
assumed to be carrying a single protocol. Since the Ethernet packets are bridged, the IAD's only
responsibility is to pass the Ethernet packets to and from the Internet Service Provider and the
local network. The IP addresses of the local network are assigned by the ISP either statically or
dynamically.
