ip local interface

ip local interface

To configure the IP address of the provider edge (PE) router interface to be used as the source IP address for sending tunneled packets, use the ip local interface command in the pseudowire-class configuration mode. To remove the IP address, use the no form of this command.

ip local interface interface-nameno ip local interface interface-name

Syntax Description	interface-name	Name of the PE interface whose IP address is used as the source IP address
		for sending tunneled packets over a Layer 2 PW.
Defaults	No IP address is configured.
Command Modes	Pseudowire-class configuration
Command History	Release	Modification
	12.0(23)S	This command was introduced.
	12.3(2)T	This command was integrated into Cisco IOS Release 12.3(2)T.
	12.4(12)MR2	This command was integrated into Cisco IOS Release 12.4(12)MR2.
Usage Guidelines	Use the same local interface name for all pseudowire-classes configured between a pair of PE routers. It
	is highly recommended that you configure a loopback interface with this command. If you do not, the
	router chooses the “best available local address,” which could be any IP address configured on a
	core-facing interface. This configuration could prevent a control channel from being established.
Note	This command must be configured for pseudowire-class configurations using L2TPv3 as the data
	encapsulation method.
Examples	The following example shows how to configure the IP address of the local loopback 0 as the source IP
	address for sending packets through an L2TPv3 session:

Router# config t

Router(config)# pseudowire-class l2tp

Router(config-pw-class)#ip local interface loopback 0

Router(config-pw-class)# exit

Router(config)# exit
