Example:
Router(config-if)# xconnect
10.0.3.201 123 pw-class
vlan-xconnect
Specifies the IP address of the peer PE router and the 32-bit virtual circuit
identifier shared between the PE at each end of the control channel.
• The peer router ID (IP address) and virtual circuit ID must be a unique
combination on the router.
• At least one of the following pseudowire class parameters must be
configured for the pseudowire-parameters argument:
– encapsulation {l2tpv3 [manual] | mpls}—Specifies the tunneling
method used to encapsulate data in the pseudowire:
• l2tpv3—L2TPv3 is the tunneling method to be used.
• manual—(Optional) No signaling is to be used in the L2TPv3 control
channel. This command places the router in xconnect configuration
mode for manual configuration of L2TPv3 parameters for the
attachment circuit.
• mpls—MPLS is the tunneling method to be used.
– pw-class {pw-class-name}—The pseudowire class configuration
from which the data encapsulation type (L2TPv3) will be taken.
• The optional encapsulation parameter specifies the method of pseudowire
tunneling used: L2TPv3 or MPLS. Enter manual if you do not want
signaling used in the L2TPv3 control channel. The encapsulation l2tpv3
manual keyword combination enters xconnect configuration submode.
See the section “Manually Configuring L2TPv3 Session Parameters” for
the other L2TPv3 commands that you must enter to complete the
configuration of the L2TPv3 control channel. If you do not enter an
encapsulation value, the encapsulation method entered with the
password command in the section “Configuring the Xconnect Attachment
Circuit” is used.
• The optional pw-class parameter binds the Xconnect statement to a
specific pseudowire class. The pseudowire class then serves as the
template configuration for all attachment circuits bound to it. Specify the
pseudowire-class option if you need to configure more advanced options.
Note You must configure either the encapsulation or the pw-class option.
You may configure both options.
Note If you select L2TPv3 as your data encapsulation method, you must
specify the pw-class keyword.
• The optional sequencing parameter specifies whether sequencing is
required for packets that are received, sent, or both received and sent.
