A single physical link can have multiple prefixes assigned to it. In
that environment, end hosts might have multiple IP addresses and be
required to use them selectively. RFC 3484 defines default source
and destination address selection rules and is implemented in a
variety of OSs. But, it has been too difficult to use operationally
for several reasons. In some environments where multiple prefixes are
assigned on a single physical link, the host using the default
address selection rules will experience some trouble in
communication. This document describes the possible problems that
end hosts could encounter in an environment with multiple prefixes. This
memo provides information for the Internet community.
