Configuring the Encapsulation and LMI

To configure the Frame Relay encapsulation and LMI, follow these steps:

Enable Frame Relay encapsulation on the interface using the encapsulation frame-relay command.

Configure the LMI type on the interface using the frame-relay lmi-type command. The default LMI type is Cisco, but you can also use ANSI or Q933a.

Configure the Frame Relay DLCI on the interface using the frame-relay interface-dlci command.

(Optional) Configure Frame Relay subinterfaces if you want to divide the main interface into multiple logical interfaces.

Here is an example configuration:

interface Serial0/0

encapsulation frame-relay

frame-relay lmi-type cisco

frame-relay interface-dlci 100

In this example, the Frame Relay encapsulation is enabled on Serial0/0 interface, the LMI type is set to Cisco, and the DLCI is set to 100.

To verify the Frame Relay configuration, you can use the following commands:

show interfaces serial 0/0: This command shows the interface configuration, including the encapsulation and DLCI.

show frame-relay lmi: This command shows the LMI status, including the LMI type and the DLCI used for LMI.

show frame-relay map: This command shows the mapping between the local DLCIs and the remote addresses.

show frame-relay pvc: This command shows the PVC status, including the DLCI, the PVC status, and the traffic statistics.

Make sure that the local and remote Frame Relay configurations match and that the DLCIs are configured correctly on both ends.
