The Rf API is packaged as a Diameter application similar to the Sh application used for managing profile data. The Rf Diameter API can be configured and enabled by editing the Diameter configuration file located in Domain_Home/config/custom/diameter.xml, or by using the Diameter console extension. Additionally, configuration of both the CDF realm and host can be specified using the cdf.realm and cdf.host initialization parameters to the Diameter Rf application.

Example 3-3 shows a sample excerpt from diameter.xml that enables Rf with a CDF realm of "example.com" and host "cdf.example.com:"
