Abstract

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.
