LMI is a set of signalling standards between routers and Frame Relay switches. Communication takes place between a router and the first Frame Relay switch to which it is connected. Information about keepalives, global addressing, IP multicast and the status of virtual circuits is commonly exchanged using LMI.
There are three standards for LMI:
Carrier Ethernet
