Chapter 20 Configuring L2 Virtual Private Networks
To set up a pseudowire connection or AToM circuit between two PE routers, enter the following
commands beginning in global configuration mode:
Command
Step 1
Router(config)# pseudowire-class name
Step 2
Router(config)# interface interface-type
interface-number
Step 3
Router(config-if)# encapsulation
encapsulation-type
Step 4
Router(config-if)# xconnect peer-router-id
vcid encapsulation mpls
Example 20-2
on 0/100 is configured for AAL5 transport.
Example 20-2 ATM AAL5 SDU Support over MPLS

xconnect 13.13.13.13 100 encapsulation mpls
Purpose
(Optional) Establishes a pseudowire class with a name that you
specify and specifies the tunneling encapsulation. It is not
necessary to specify a pseudowire class if you specify the
tunneling method as part of the xconnect command.
The pseudowire-class configuration group specifies the
characteristics of the tunneling mechanism, including:
Encapsulation type
•
Control protocol
•
Payload-specific options
•
Defines the interface or subinterface on the PE router.
Specifies the encapsulation type for the interface, such as
dot1q.
Makes a connection to the peer PE router by specifying the
LDP router ID of the peer PE router.
Identifies a unique identifier that is shared between the two
PE routers. The vcid is a 32-bit identifier.
The combination of the peer-router-id and the VC ID
Note
must be a unique combination on the router. Two
circuits cannot use the same combination of
peer-router-id and VC ID.
Specifies the tunneling method used to encapsulate data in the
pseudowire. For AToM, the tunneling method used to
encapsulate data is mpls.
