Abstract

This document defines new RADIUS accounting Attributes and new values

for the existing Acct-Status-Type Attribute [1] designed to support

the provision of compulsory tunneling in dial-up networks.

Specification of Requirements

In this document, the key words "MAY", "MUST, "MUST NOT", "optional",

"recommended", "SHOULD", and "SHOULD NOT", are to be interpreted as

described in [2].

1. Introduction

Many applications of tunneling protocols such as PPTP [5] and L2TP

[4] involve dial-up network access. Some, such as the provision of

secure 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, as a service of the Internet service provider (ISP).

Typically, ISPs providing a service want to collect data regarding

that service for billing, network planning, etc. One way to collect

usage data in dial-up networks is by means of RADIUS Accounting [1].

The use of RADIUS Accounting allows dial-up usage data to be

collected at a central location, rather than stored on each NAS.

In order to collect usage data regarding tunneling, new RADIUS

attributes are needed; this document defines these attributes. In

addition, several new values for the Acct-Status-Type attribute are

proposed. Specific recommendations for, and examples of, the

application of this attribute for the L2TP protocol can be found in

RFC 2809.

2. Implementation Notes

Compulsory tunneling may be part of a package of services provided by

one entity to another. For example, a corporation might contract
