Abstract

   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 can be introduced at any
   time.
