IEEE 802.1Qca Path Control and Reservation (PCR) [IEEE8021Qca] specifies extensions to IS-IS for the control of Explicit Trees (ETs). The PCR extensions are compatible with the Shortest Path Bridging (SPB) extensions to IS-IS specified by [RFC6329] and [IEEE8021aq] (already rolled into [IEEE8021Q]). Furthermore, IS-IS with PCR extensions relies on the SPB architecture and terminology, and some of the IS-IS SPB sub-TLVs are also leveraged. IS-IS PCR builds upon IS-IS and uses IS-IS in a similar way to SPB. IS-IS PCR only addresses point-to-point physical links, although IS-IS also supports shared media LANs.

                    IS-IS Path Control and Reservation


   IEEE 802.1Qca Path Control and Reservation (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.  This document specifies the sub-TLVs for IS-IS PCR.
