Considerations on the Application of the
Level 3 Multihoming Shim Protocol for IPv6 (Shim6)
Abstract
This document discusses some considerations on the applicability of
the level 3 multihoming Shim protocol for IPv6 (Shim6)
and associated support protocols and mechanisms to provide site
multihoming capabilities in IPv6.
