This document gives guidance on securing IPv6-in-IPv4 tunnels using IPsec. No additional protocol extensions are described beyond those available with the IPsec framework. This document describes packet formats, IPsec security policy database for various scenarios, address configuration procedures, and the usage of the Extensible Authentication Procotol.
