ip local interface
ip local interface
To configure the IP address of the provider edge (PE) router interface to be used as the sourc e 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-name
no ip local interface interface-name
Syntax Description
Defaults No IP address is configured.
Command Modes Pseudowire-class configuration
Command History
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 comman d. If you do not, the
router chooses the “best available local address,” which could be any IP address co nfigured 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 us ing 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
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.
