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

It is stable, without changes to the technical solution for more
