   The IP Router Alert Option is an IP option that alerts transit
   routers to more closely examine the contents of an IP packet.
   Resource reSerVation Protocol (RSVP), Pragmatic General Multicast
   (PGM), Internet Group Management Protocol (IGMP), Multicast Listener
   Discovery (MLD), Multicast Router Discovery (MRD) and General
   Internet Signalling Transport (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 thereby updating RFC2113 and RFC2711.
   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.
