Hi authors, The I-D “draft-ietf-idr-segment-routing-te-policy” defines sub-tlvs for SR Policy attributes that are carried in BGP (see below) for SR policy and its attributes. Ideally, with PCEP can achieve what is supported with BGP signaling and hence can leverage the most of those definitions? Is there a reason not to?
