Abstract:
   In theory routing decisions on the Internet and by extension within
   ISP networks should always use hot-potato routing to reach any given
   destination.  In reality operators sometimes choose to not use the
   hot-potato paths to forward traffic due to a variety of reasons,
   mostly motivated by traffic engineering considerations.  For prefixes
   carrying anycast traffic in virtually all situations it is advisable
   to stick to the hot-potato principle.  As operators mostly don't know
   which prefixes are carrying unicast or anycast traffic, they can't
   differentiate between them in their routing policies.

   To allow operators to take well informed decisions on which prefixes
   are carrying anycast traffic this document proposes a well-known BGP
   community to denote this property.
