Configuring EoA Interfaces
The Ethernet-over-ATM (EoA) protocol is often referred to as
RFC1483 , which is the Internet specification that defines it. It is
commonly used to carry data from an Ethernet-based local area
network over the ATM-based wide area network.
Unlike PPP, EoA can be implemented to provide a bridged
connection between a DSL modem and the ISP. In a bridged
connection, data is shared between the ISP’s network and their
customer’s as if the networks were on the same physical LAN.
Bridged connections do not use the IP protocol. EoA can also be
configured to provide a routed connection with the ISP, which uses
the IP protocol to exchange data. See Chapter 6 “Configuring the
System Operating Mode,” for more information on bridged and
routed Internet connections.
Before creating an EoA interface or modifying the default settings,
contact your ISP to determine which type of protocol they use.
Note
PPP and EoA: Bridged Internet connections must use an EoA
WAN interface. Routed Internet connections can use an EoA (if
configured with an IP address) or a PPP interface. See Chapter 5
for more information.
To view your current EoA interface configuration, log into Web
Configuration, click the WAN tab, and then click
EOA
in the task bar.

The EoA table contains a row for each EoA interface currently
defined on the device. The table may be empty.
