The IESG has received a request from the Open Shortest Path First IGP WG (ospf) to consider the following document: - 'Supporting Authentication Trailer for OSPFv3' <draft-ietf-ospf-rfc6506bis-01.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-11-26. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Currently, OSPF for IPv6 (OSPFv3) uses IPsec as the only mechanism for authenticating protocol packets. This behavior is different from authentication mechanisms present in other routing protocols (OSPFv2, Intermediate System to Intermediate System (IS-IS), RIP, and Routing Information Protocol Next Generation (RIPng)). In some environments, it has been found that IPsec is difficult to configure and maintain and thus cannot be used. This document defines an alternative mechanism to authenticate OSPFv3 protocol packets so that OSPFv3 does not only depend upon IPsec for authentication. This document obsoletes RFC 6506. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-ospf-rfc6506bis/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-ospf-rfc6506bis/ballot/ No IPR declarations have been submitted directly on this I-D.
