.bp .HDR_1 Introduction 

The Service Location Protocol, Version 2 [rfc2608bis] provides a
flexible and scalable framework for provisioning network nodes with
information on the existence, location, and configuration of networked
services.

[rfc2608bis] recommends using [IPSEC] to provide authentication and
privacy to SLP messages, transported either upon UDP or TCP. [IPSEC]
SHOULD be used with SLP. 

This document outlines optional protocol extensions that MAY be used
for authenticating SLP messages when [IPSEC] is not available in the
environment. 

As with all SLP protocol extensions, support for the signature
extension is OPTIONAL and cannot be assumed present in the
computing environment. 

.HDR_2 Need\ for\ Authentication\ of\ SLP\ Messages

[rfc2608] outlines the need for authentication of SLP messages in
section 15.
