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 20-23 shows how to enable Frame Relay over MPLS with port-to-port connections.
Example 20-23 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.
Command Purpose
Command 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.
