CONFIGURATION SETTINGS

•PPPoE VC-Mux. Point to Point Protocol over Ethernet Virtual Circuit Multiplexer uses PPP to bridge multiprotocol traffic over Ethernet to the ISP’s router. Each PPP connection first learns the Ethernet address of its remote peer, and then establishes a unique session identifier.

•PPPoE LLC. Point to Point Protocol over Ethernet Logical Link Control allows multiple protocols running over one virtual circuit with a little bit more overhead

•PPPoE None.

Your service provider will tell you which connection type to use.

Protocol Multiplexing

Protocol multiplexing allows you access a remote site using protocols such as IP, Novell IPX, or Windows NetBuei networks just as though you were attached to the local LAN. Also, note that all broadcast and multicast frames entering the LAN port are always forwarded to the ADSL port.

Some of the encapsulation methods provided by this router support two methods for carrying traffic over an ATM connection. LLC (Logical Link Control) Encapsulation allows multiplexing of multiple protocols over a single virtual circuit, where each data packet contains an extra field identifying the protocol. While VC Based Multiplexing carries each protocol over a separate virtual circuit and therefore does not need to include any explicit information identifying the protocol type.

Since VC multiplexing does not include the additional protocol identifiers used in LLC encapsulation, you should use this method whenever possible to maximize bandwidth utilization. If your ISP only supports one Virtual Circuit, use VC multiplexing unless more than one protocol is carried over the link. You should also use VC multiplexing with encapsulation methods such as IP/ATM which only requires one transport protocol.
