The IESG has received a request from the Open Shortest Path First IGP WG (ospf) to consider the following document: - 'Hiding Transit-only Networks in OSPF' <draft-ietf-ospf-prefix-hiding-04.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 2012-07-06. 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 A transit-only network is defined as a network connecting routers only. In OSPF, transit-only networks are usually configured with routable IP addresses, which are advertised in Link State Advertisements (LSAs) but not needed for data traffic. In addition, remote attacks can be launched against routers by sending packets to these transit-only networks. This document presents a mechanism to hide transit-only networks to speed up network convergence and minimize remote attack vulnerability. This document updates RFC 2328 and RFC 5340. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-ospf-prefix-hiding/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-ospf-prefix-hiding/ballot/ The following IPR Declarations may be related to this I-D: http://datatracker.ietf.org/ipr/1798/
