Network Working Group F. Gont Internet-Draft UTN-FRH / SI6 Networks Intended status: Standards Track October 4, 2012 Expires: April 7, 2013 Obsoleting the Endpoint Identifier (EID) Option draft-gont-intarea-obsolete-eid-option-01 Abstract This document formally deprecates the IPv6 Endpoint Identification (EID) option (hex value 0x8a), thus cleaning up the corresponding IANA registry, and possibly serving as a basis for providing advice about the filtering of packets containing this option.

Introduction The Endpoint Identification option (hex value 0x8a) [EID-OPTION] was meant to be used with the Nimrod routing architecture [NIMROD-DOC], but has never seen widespread deployment. Therefore, this document instructs IANA to change the "Destination Options and Hop-by-Hop Options" registry [IANA-IPV6-PARAMETERS] accordingly (marking option 0x8a as "Obsolete"), thus cleaning up the corresponding registry. Gont Expires April 7, 2013 [Page 3] Internet-Draft Obsoleting the EID Option October 2012 2. Security Considerations This document does not modify the security properties of the IPv6 option being deprecated. However, formally deprecating this option may serve as a basis for e.g. providing advice about filtering packets containing such option (in a similar way to [I-D.ietf-opsec-ip-options-filtering] for the IPv4 case). Gont Expires April 7, 2013 [Page 4] Internet-Draft Obsoleting the EID Option October 2012 3. IANA Considerations The "Destination Options and Hop-by-Hop Options" registry [IANA-IPV6-PARAMETERS] contains the list of the currently assigned IPv6 option numbers. This document formally deprecates the Endpoint Identification option, and requests IANA to mark it as such in the corresponding registry [IANA-IPV6-PARAMETERS].
