Abstract
This document specifies the way of encapsulating IPv6, IPv4, and
Address Resolution Protocol (ARP) packets over Fibre Channel. This
document also specifies the method of forming IPv6 link-local
addresses and statelessly autoconfigured IPv6 addresses on Fibre
Channel networks, and a mechanism to perform IPv4 address resolution
over Fibre Channel networks.
This document obsoletes RFC 2625 and RFC 3831.
