http://www.cisco.com/en/US/docs/internetworking/troubleshooting/guide/tr1918.htm #wp1020573lLMI ExtensionsIn addition to the basic Frame Relay protocol functions for transferring data, the consortium Frame Relay specification includes LMI extensions that make supporting large, complex internetworks easier. Some LMI extensions are referred to as "common" and are expected to be implemented by everyone who adopts the specification. Other LMI functions are referred to as "optional." A summary of the LMI extensions follows:•Virtual circuit status messages (common)—Provide communication and synchronization between the network and the user device, periodically reporting the existence of new PVCs and the deletion of already existing PVCs, and generally provide information about PVC integrity. Virtual circuit status messages prevent the sending of data into black holes—that is, over PVCs that no longer exist.•Multicasting (optional)—Allows a sender to transmit a single frame but have it delivered by the network to multiple recipients. Thus, multicasting supports the efficient conveyance of routing protocol messages and address resolution procedures that typically must be sent to many destinations simultaneously.•Global addressing (optional)—Gives connection identifiers global rather than local significance, allowing them to be used to identify a specific interface to the Frame Relay network. Global addressing makes the Frame Relay network resemble a local-area network (LAN) in terms of addressing; Address Resolution Protocols, therefore, perform over Frame Relay exactly as they do over a LAN.•Simple flow control (optional)—Provides for an XON/XOFF flow control mechanism that applies to the entire Frame Relay interface. It is intended for devices whose higher layers cannot use the congestion notification bits and that need some level of flow control.
