Configuration of Service Translation

To enable service translation on the router, enter the following command in global configuration mode:

Command	Purpose

Router(config)# ssg service-overlap	Enables service translation and indicates to the router to use the
	translated sets to provide the desired network behavior.

Configuration Example for Service Translation

The following example shows how the service translation mechanism translates the services defined in SESM to sets (for example, service networks). The router uses the sets internally to provide the desired behavior.
