A Segment Routed Path can be derived from a variety of mechanisms, including an IGP Shortest Path Tree (SPT), explicit configuration, or a Path Computation Element(PCE). Since SR can be applied to both MPLS and IPv6 data-planes, a PCE should be able to compute an SR Path for both MPLS and IPv6 data- planes. The Path Computation Element communication Protocol (PCEP) extension and mechanisms to support SR-MPLS have been defined. This document outlines the necessary extensions to support SR for the IPv6 data-plane within PCEP.}, }
