Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: Internet Architecture Board <email@example.com>, RFC Editor <firstname.lastname@example.org> Subject: Document Action: 'Calculating IGP Routes Over Traffic Engineering Tunnels' to Informational RFC The IESG has approved the following document: - 'Calculating IGP Routes Over Traffic Engineering Tunnels ' <draft-ietf-rtgwg-igp-shortcut-02.txt> as an Informational RFC This document is the product of the Routing Area Working Group. The IESG contact persons are Alex Zinin and Ross Callon. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-rtgwg-igp-shortcut-02.txt
Technical Summary This document describes how conventional hop-by-hop link-state routing protocols interact with MPLS Traffic Engineering capabilities to create IGP shortcuts. In particular this document describes how Dijkstra's SPF algorithm can be adapted so that link-state IGPs will calculate IP routes to forward traffic over tunnels that are set up by Traffic Engineering. Working Group Summary The document started as an individual submission that was later accepted as a WG item in RTGWG. It has undergone substantial technical review by individuals within the RTGWG and reflects the discussion on the mailing list. It has passed the WG LC. Protocol Quality The mechanisms described in the document have been implemented and deployed. The specification has been review for IESG by Alex Zinin.
