xconnect
xconnect
To bind an attachment circuit to a pseudowire (PW), use the xconnect command in one of the supported
configuration modes. To restore the default values, use the no form of this command.
xconnect peer-ip-address | vcid | pseudowire-parameters [sequencing {transmit | receive | both |
one-to-one}] [ignore-vpi-vci]
Syntax Description
Defaults The attachment circuit is not bound to the PW.
Command Modes CEM circuit configuration
Interface configuration
Subinterface configuration
peer-ip-address IP address of the remote provider edge (PE) peer.
vcid The 32-bit identifier of the virtual circuit between the PE routers.
pseudowire-parameters Encapsulation and pseudowire-class parameters to be used for the
attachment circuit. At least one of the following PW parameters must be
configured:
• encapsulation {l2tpv3 | mpls}— Specifies the tunneling method to
encapsulate the data in the PW:
– l2tpv3—Specifies L2TPv3 as the tunneling method.
– mpls—Specifies MPLS as the tunneling method.
• pw-class pw-class-name—Specifies the pseudowire-class
configuration from which the data encapsulation type is taken. This
option is mandatory if you select an encapsulation method.
sequencing (Optional) Sets the sequencing method to be used for packets received or
sent.
Note Sequencing is not supported for CEM circuits.
transmit Sequences data packets received from the attachment circuit.
receive Sequences data packets sent into the attachment circuit.
both Sequences data packets that are both sent and received from the attachment
circuit.
one-to-one Only apply when the xconnect command is configured under the AAL0
encapsulation PVC. It specifies the PW type as a one-to-one VCC cell relay.
ignore-vpi-vci With the ignore-vpi-vci keyword configured, the MWR ignores the
VPI/VCI value in the PW packet and does a blind rewrite with the local
configured AC-side PVC's VPI/VCI value. Only apply when the xconnect
command is configured under the PVC, which is the N:1 with N=1 special
case. Do not apply when the xconnect command is configured under the
subinterface, which supports N>1.
