Technical Summary

   The IP Router Alert Option is an IP option that alerts transit
   routers to more closely examine the contents of an IP packet.  RSVP,
   PGM, IGMP/MLD, MRD and GIST are some of the protocols that make use
   of the IP Router Alert option.  This document discusses security
   aspects and usage guidelines around the use of the current IP Router
   Alert option.  Specifically, it provides recommendation against using
   the Router Alert in the end-to-end open Internet as well as identify
   controlled environments where protocols depending on Router Alert can
   be used safely.  It also provides recommendation about protection
   approaches for Service Providers.  Finally it provides brief
   guidelines for Router Alert implementation on routers.
