MAC layer addresses are pre-pended in the ethernet header over the Wide Area Connections. Address Resolution procedures (ARP), are used to dynamically learn the MAC address of the remote router.

Site?and/or bridge other protocols between workstations on the Local Area Network (LAN) and up to 16 remote locations over an ATM or Frame Relay Wide Area Network (WAN). This is illustrated in the diagram below, showing the local LAN simultaneously connected to a remote office and the Internet.

Data is transmitted to and from remote sites through ATM or Frame Relay. With ATM, each VC has a configured Quality of Service (QOS) and is identified by a Virtual Path Identifier (VPI) and a Virtual Channel Identifier (VCI). With Frame Relay, each Virtual Circuit is identified by a DLCI. Obtain these parameters from your Service Provider.

The data is framed in either PPP, RFC 1483 or RFC 1490 encapsulation, which also is specified by your Service Provider.

The IP, IPX, and bridge protocols transmit over the ATM VCs. When a remote site is configured to route IP, there will be a corresponding remote network IP subnet address and (optionally) a local WAN interface address
