mpls control-word
mpls control-word
To enable the Multiprotocol Label Switching (MPLS) control word in an Any Transport over MPLS
(AToM) static pseudowire connection, use the mpls control-word command in xconnect configuration
mode. To disable the control word, use the no form of this command.
mpls control-word
no mpls control-word
Syntax Description This command has no arguments or keywords.
Command Default The control word is included in connections.
Command Modes Xconnect configuration
Command History
Usage Guidelines This command is used when configuring AToM static pseudowires, and is mandatory when configuring
Frame Relay data-link connection identifier (DLCI) and ATM adaptation layer 5 (AAL5) attachment
circuits.
Because the control word is included by default, it may be necessary to explicitly disable this command
in AToM static pseudowire configurations.
When the mpls control-word command is used in static pseudowire configurations, the command must
be configured the same way on both ends of the connection to work correctly, or else the provider edge
routers cannot exchange control messages to negotiate inclusion or exclusion of the control word.
Examples The following example shows the configuration for both sides of an AToM static pseudowire
connection:
Router# configure terminal
Router(config)# interface Ethernet 1/0
Router(config-if)# xconnect 10.131.191.251 100 encapsulation mpls manual pw-class mpls
Router(config-if-xconn)# mpls label 100 150
Router(config-if-xconn)# no mpls control-word
Router(config-if-xconn)# exit
Router(config-if)# exit
Router# configure terminal
Router(config)# interface Ethernet 1/0
Router(config-if)# xconnect 10.132.192.252 100 encapsulation mpls manual pw-class mpls
Router(config-if-xconn)# mpls label 150 100
