encapsulation l2tpv3
encapsulation l2tpv3
To specify that Layer 2 Tunnel Protocol version 3 (L2TPv3) is used as the data encapsulation method
for tunneling IP traffic over the PW, use the
encapsulation l2tpv3 command in pseudowire-class
configuration mode. To remove L2TPv3 as the encapsulation method, use the no pseudowire-class
command (see the Usage Guidelines for more information).
encapsulation l2tpv3
no pseudowire-class
Syntax Description
This command has no arguments or keywords.
Defaults No encapsulation method is specified.
Command Modes Pseudowire-class configuration
Command History
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-class command. To
change the type of encapsulation, remove the PW with the no pseudowire-class comm and 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
