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.
