What identifies a logical circuit and is locally significant between the router and the local Frame Relay switch?

  2. an LMI signal
  3. an FECN packet
  4. a BECN packet

 

The correct answer is A.

The data link connection identifier (DLCI) is a locally significant number between the router and the local Frame Relay switch that identifies a logical virtual connection. Devices at opposite ends of a virtual circuit may use different DLCIs to refer to the virtual circuit.
