Abstract This document defines a set of RADIUS attributes designed to support the provision of compulsory tunneling in dial-up networks. 1. Motivation Many applications of tunneling protocols such as L2TP involve dial-up network access. Some, such as the provision of access to corporate intranets via the Internet, are characterized by voluntary tunneling: the tunnel is created at the request of the user for a specific purpose. Other applications involve compulsory tunneling: the tunnel is created without any action from the user and without allowing the user any choice in the matter. In order to provide this functionality, new RADIUS attributes are needed to carry the tunneling information from the RADIUS server to the tunnel end points; this document defines those attributes. Specific recommendations for, and examples of, the application of these attributes for L2TP can be found in RFC 2809. Zorn, et al. Informational
