Introduction Fibre Channel (FC) is a high speed serial interface technology that supports several Upper Layer Protocols including Small Computer System Interface (SCSI) and IPv4 as specified in [IPFC]. The purpose of this document is to specify a way of encapsulating IP version 6 [IPv6] over Fibre Channel and to describe a method of forming IPv6 link-local addresses [AARCH] and statelessly autoconfigured addresses on Fibre Channel networks. This document also describes the content of the Source/Target Link-layer Address option used in Neighbor Discovery [DISC] when the messages are transmitted on a Fibre Channel network. Warning to readers familiar with Fibre Channel: both Fibre Channel and IETF standards use the same byte transmission order. However, the bit numbering is different. See Appendix C for guidance. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [KEYWORDS].Show full document text
