The IESG has approved the following document: - 'IS-IS Path Computation and Reservation' (draft-ietf-isis-pcr-05.txt) as Proposed Standard This document is the product of the IS-IS for IP Internets Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-isis-pcr/ Technical Summary This is a liason document coming from the IEEE 802.1Qca Path Control and Reservation (PCR) STO group. PCR specifies explicit path control via IS-IS in Layer 2 networks in order to move beyond the shortest path capabilities provided by IEEE 802.1aq Shortest Path Bridging (SPB). IS-IS PCR provides capabilities for the establishment and control of explicit forwarding trees in a Layer 2 network domain. Working Group Summary All that IEEE PCR need is codepoints for their protocol extension. Since ISIS-wg is now the sole gatekepeer for IS-IS codepoints, we have asked the PCR group to come up with a short draft how these code points are used. There has not been much controversy around extending IS-IS in support of Layer-2 explicit trees. Document Quality This document has been a WG document for more than 6 months. It is stable, without changes to the technical solution for more than 6 months. Personnel Hannes Gredler is the Document Shepherd. Alia Atlas is the Responsible Area Director. RFC Editor Note Please allocate as soon as possible the RFC number. There is an IEEE document dependent on a reference and it is held back only until February. Thanks!
