ip protocol Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference 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 l2tp uti udp (Default) Configures L2TP as the IP protocol used to tunnel packets in a Layer 2 PW. 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. Configures UDP as the IP protocol used to tunnel packets in a Layer 2 PW. Defaults The default IP protocol is L2TP. Command Modes Pseudowire-class configuration Command History Release 12.0(23)S 12.3(2)T 12.4(12)MR2 Modification This command was introduced. This command was integrated into Cisco IOS Release 12.3(2)T. This command was integrated into Cisco IOS Release 12.4(12)MR2. 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 Command pseudowire-class Description Specifies the name of an L2TP pseudowire-class and enters pseudowire-class configuration mode.
