Layer 2 Tunnel Protocol Version 3

Cisco IOS Releases 12.0(29)S and 12.2(25)S
protocol
To specify the signaling protocol to be used to manage the pseudowires created from a pseudowire class
for a dynamic Layer 2 Tunnel Protocol Version 3 (L2TPv3) session, and that control plane configuration
settings are to be taken from a specified L2TP class, use the protocol command in pseudowire class
configuration mode. To remove the signaling protocol (and the control plane configuration to be used)
for a pseudowire class, use the no form of this command.
protocol {l2tpv3 | none} [l2tp-class-name]
no protocol {l2tpv3 | none} [l2tp-class-name]
Syntax Description
Defaults The default protocol option is l2tpv3.
If you do not enter a value for the l2tp-class-name argument, the default control plane configuration
settings in the L2TP signaling protocol are used.
Command Modes Pseudowire class configuration
Command History
Usage Guidelines Use the protocol l2tpv3 command to configure L2TPv3 as the signaling protocol to use in dynamic
L2TPv3 sessions created from the specified pseudowire class. In addition, you can use this command to
specify the L2TP class (see the section “Configuring the Xconnect Attachment Circuit”) from which the
control plane configuration settings are to be taken for use in a dynamic L2TPv3 session.
Use the protocol none command to specify that no signaling will be used in L2TPv3 sessions created
from the specified pseudowire class. This configuration is required for interoperability with a remote
peer running the Universal Tunnel Interface (UTI).
Do not use the command if you want to configure a pseudowire class used to create manual L2TPv3
sessions (see the section “Static L2TPv3 Sessions”).
l2tpv3 Specifies that L2TPv3 signaling protocol will be used in L2TPv3 sessions.
none Specifies that no signaling protocol will be used in L2TPv3 sessions.
l2tp-class-name (Optional) The name of the L2TP class whose control plane configuration
is to be used for pseudowires in dynamic L2TPv3 sessions set up from a
specified pseudowire class.
