PurposeCommand or Action
(Optional) Defines the operating characteristics for the CEM circuit. For
command details, see the Configuring CEM Parameters, on page 533.
Router(config-if-cem)# command
Step 3
Configures a pseudowire to transport TDM data from the CEM circuit across
the MPLS network.
Router(config-if)# xconnect
peer-router-id vcid {encapsulation
mpls | pw-class name }
Step 4
•
peer-router-id is the IP address of the remote PE peer router.
•
vcid is a 32-bit identifier, which is assigned to the pseudowire. The same
vcid must be used for both ends of the pseudowire.
•
encapsulation mpls sets MPLS for the tunneling mode.
•
pseudowire-class name specifies a pseudowire class that includes the
encapsulation mpls command.
The peer-router-id and vcid combination must be unique on the
router.
Note
Exits interface configuration mode.Router(config-if)# exit
Step 5
What to Do Next
Example
The following sample configuration shows a T1 port on which two CEM circuits (groups) are configured.
Each CEM circuit carries data from the time slots of the TDM circuit attached to the port.
The two xconnect commands create pseudowires to carry the TDM data across the MPLS network. Pseudowire
2 carries the data from time slots 1, 2, 3, 4, 9, and 10 to the remote PE router at 10.10.10.10. Pseudowire 5
carries the data from time slots 5, 6, 7, 8, and 11 to the remote PE router at 10.10.10.11.
