Usage Guidelines This command must be configured if the pseudowire-class is referenced from an xconnect configured to forward L2TPv3 traffic.

Once you specify the encapsulation l2tpv3 command, you cannot remove it using the no encapsulation l2tpv3 command. Nor can you change the command’s setting using the encapsulation mpls command. Those methods result in the following error message:

Encapsulation changes are not allowed on an existing pw-class.

To remove the l2tpv3 command, you must delete the PW with the no pseudowire-classcommand. To change the type of encapsulation, remove the PW with the no pseudowire-class command to re-establish the PW and to specify the new encapsulation type.

Examples The following example illustrates the use of the encapsulation l2tpv3 command:

Router# config t

Router(config)# pseudowire-class l2tp

Router(config-pw-class)# encapsulation l2tpv3

Router(config-pw-class)# exit

Router(config)# exit
