SR enables any head- end node to select any path without relying on a hop-by-hop signaling technique (e.g., LDP or RSVP-TE). A Segment Routed Path can be derived from a variety of mechanisms, including an IGP Shortest Path Tree (SPT), explicit configuration, or a PCE. Since SR can be applied to both MPLS and IPv6 forwarding planes, a PCE should be able to compute SR-Path for both MPLS and IPv6 forwarding planes. The PCEP extension and mechanisms to support SR- MPLS have been defined. This document describes the extensions required for SR support for IPv6 data plane in the Path Computation Element communication Protocol (PCEP).}, }
