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.
