LMI is a signaling standard used between [[routers]] and [[frame relay]] switches. Communication takes place between a router and the first frame relay switch it's connected to. Information about [[keepalive]]s, global addressing, [[multicasting]] and the status of [[virtual circuits]] is commonly exchanged using LMI.

There are three standards Thefor LMI: ANSI's Annex D standard, T1.617, ITU-T's Q.933 Annex A standard, and the "Gang of Four" standard, named for the four companies that developed it: Cisco, DEC, StrataCom and NorTel (Northern Telecom).
