The IESG has received a request from the Open Shortest Path First IGP WG (ospf) to consider the following document: - 'Advertising Tunneling Capability in OSPF' <draft-ietf-ospf-encapsulation-cap-06.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 2017-08-28. 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 Networks use tunnels for a variety of reasons. A large variety of tunnel types are defined and the ingress needs to select a type of tunnel which is supported by the egress and itself. This document defines how to advertise egress tunnel capabilities in OSPF Router Information Link State Advertisement (LSAs). The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-ospf-encapsulation-cap/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-ospf-encapsulation-cap/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: draft-ietf-idr-tunnel-encaps: The BGP Tunnel Encapsulation Attribute (None - IETF stream)
