The Frame Relay-to-Frame Relay Local Switching feature is described in the following topics:
• Configuring Frame Relay for Local Switching, page 20-32
• Configuring Frame Relay Same-Port Switching, page 20-33
• Verifying Layer 2 Local Switching for Frame Relay, page 20-34
• Configuring QoS Features, page 20-34
Configuring Frame Relay for Local Switching
To configure Frame Relay for local switching, enter the following commands, beginning in global
configuration mode.
Example 20-24 configures Frame-Relay-to-Frame-Relay for local switching.

Command Purpose
Step 1
Router(config)# frame-relay switching
Enables Permanent Virtual Circuits (PVCs) switching on a
Frame Relay DCE device or a Network-to-Network
Interface (NNI).
Step 2
Router(config)# interface type number
Specifies an interface and enters interface configuration
mode.
Step 3
Router(config-if)# encapsulation frame-relay
[cisco | ietf]
Enables Frame Relay encapsulation.
• cisco—Cisco’s own encapsulation (default)
• ietf—Internet Engineering Task Force (IETF) standard
(RFC 1490). Use this keyword when connecting to
another vendor's equipment across a Frame Relay
network.
Step 4
Router(config-if)# frame-relay interface-dlci
dlci switched
(Optional) Creates a switched PVC and enters Frame Relay
DLCI configuration mode.
Repeat Step 1 through Step 4 for each switched PVC.
If you do not create a Frame Relay PVC in this step, it is
automatically created in Step 6 by the connect command.
Step 5
Router(config-fr-dlci)# exit
Exits Frame Relay DLCI configuration mode and returns to
global configuration mode.
Step 6
Router(config)# connect connection-name
interface dlci interface dlci
Defines a connection between Frame Relay PVCs.
