1 Introduction

   This memo is the reference document for the Routing Policy
   Specification Language (RPSL). RPSL allows a network operator to be
   able to specify routing policies at various levels in the Internet
   hierarchy; for example at the Autonomous System (AS) level.  At the
   same time, policies can be specified with sufficient detail in RPSL
   so that low level router configurations can be generated from them.
   RPSL is extensible; new routing protocols and new protocol features
