ip protocol
To configure the Layer 2 Tunnel Protocol (L2TP) or Universal Tunnel Interface (UTI) as the IP protocol
used for tunneling packets in a Layer 2 PW, use the ip protocol command in the pseudowire-class
configuration mode. To remove the IP protocol configuration, use the no form of this command.
ip protocol {l2tp | uti | udp}
no ip protocol {l2tp | uti | udp}
Syntax Description
Defaults The default IP protocol is L2TP.
Command Modes Pseudowire-class configuration
Command History
Usage Guidelines The ip protocol uti command is not supported on the Cisco 3825 router. You can use the ip protocol
command only if you have already entered the encapsulation l2tpv3 command.
Examples The following example shows how to configure l2tp as the IP protocol used to tunnel packets in an
L2TPv3 PW created from the pseudowire-class named “l2tp”:
Router# config t
Router(config)# pseudowire-class l2tp
Router(config-pw-class)# encapsulation l2tpv3
Router(config-pw-class)# ip protocol l2tp
Router(config-pw-class)# exit
Router(config)# exit
Related Commands
l2tp (Default) Configures L2TP as the IP protocol used to tunnel packets in a
Layer 2 PW.
uti Configures UTI as the IP protocol used to tunnel packets in a Layer 2 PW
and allows a router running L2TPv3 to interoperate with a peer running UTI.
udp Configures UDP as the IP protocol used to tunnel packets in a Layer 2 PW.
