Configuring Frame Relay over MPLS with Port-to-Port Connections

When you set up a port-to-port connection between PE routers, you use HDLC mode to transport the
Frame Relay encapsulated packets. Perform this task to set up Frame Relay port-to-port connections.

To configure Frame Relay over MPLS with port-to-port connections, enter the following commands
beginning in global configuration mode:

Example 18-23

shows how to enable Frame Relay over MPLS with port-to-port connections.

Example 18-23 Frame Relay over MPLS With Port-to-Port Connections

interface serial5/0

encapsulation hdlc

xconnect 10.0.0.1 123 encapsulation mpls

Step 6

Router(config)# connect connection-name

interface dlci l2transport

Defines connections between Frame Relay PVCs and enters
connect submode. Using the l2transport keyword specifies that
the PVC will not be a locally switched PVC, but will be
tunneled over the backbone network.

The connection-name argument is a text string that you provide.

The interface argument is the interface on which a PVC
connection is defined.

The dlci argument is the DLCI number of the PVC that will be
connected.

Step 7

Router(config-fr-pw-switching)# xconnect

peer-router-id vcid encapsulation mpls

Creates the VC to transport the Layer 2 packets.

In a DLCI-to DLCI connection type, Frame Relay over MPLS
uses the xconnect command in connect submode.

Purpose

Step 1

Router(config)# interface serial

slot/port

Specifies a serial interface and enters interface configuration
mode.

Step 2

Router(config-if)# encapsulation hdlc

Specifies that Frame Relay PDUs is encapsulated in
HDLC packets.

Step 3

Router(config-if)# xconnect

peer-router-id vcid encapsulation mpls

Creates the VC to transport the Layer 2 packets.
