The continuous growth of routing tables in the core of Internet is a
challenge. It would become overwhelming if each multihomed customer
site would need a provider independent prefix to take full advantage
of its multihoming. IPv6 has the potential to solve this problem,
but a complete specification is still missing. This draft proposes
an approach for a solution.
The Stateless Address Mapping (SAM) model, introduced for this, is
applicable to a hierarchy of routing zones with multihoming permitted
at each level, and with each zone using local addresses for its
internal routing plan. End-to-end transparency of the Internet is
maintains across these local-address zones, thanks to a systematic
encapsulation of global-address packets into local-address packets.
Local addresses are statelessly derived from prefixes found in global
addresses, and from static parameters of traversed zones. Global
prefixes delegated by a zone to its child interfaces can be obtained
by autoconfiguration, thanks to to a bidirectional correspondence
between SAM local addresses and SAM global prefixes.
Deployment can be incremental.
