T-SDN CFP 3.0.0 - PCE-Initiated / PCC-Initiated provisioning flows: Hi All,We are working on an SDN project for Telefonica Germany and Brasil for thecustomization of T-SDN CFP 3.0.0 for L3VPN and L2VPN services withclassic MPLS underlay and TE underlay with these components:VPN Service - IETF L3NM and L2NM ModelsTE Transport - RSVP-TE/IETF-TE Model and SR-TE PolicySDN Orchestration and Automation - CNC 3.0 + SR-PCEThe scope of the project is to have a productized and supported implementation ofNSO + T-SDN CFP 3.0.0 + SDK + CNC suite + SR-PCE + OpenConfig NEDThe project has some complexity in the Automation design and implementationfor the T-SDN CFP 3.0.0 and CNC components alignment/customization, especiallyfor making CNC aware of deviated/customer specific IETF YANG models.please I would need an help to understand the provisioning flows in this setup:CNC (COE+CDG) + NSO + T-SDN CFP 3.0.0 + SR-TEI am looking into the code for T-SDN 3.0 CFP, but cannot find a final flow logicfor the IETF-TE and SR-TE provisioning in case of PCE-Initiated vs PCC-Initiated.Q1) Please do you have a documentation about this?Q2) I found PCE-Initiated JSON payloads, but please do you have an example about PCC-Initiated JSON payloads?Please could you confirm:Q3) For PCE-Initiated policies, is this the flow? > COE + NSO with T-SDN CRUD to SR-PCE with REST API &#8211; SR-PCE to devices with PCEPQ4) For PCC-Initiated policies, is this the flow? > COE + NSO with T-SDN CRUD to devices with NSO templates and NED (yellow path in the attached diagram)Q5) Which is the trigger or YANG leaf to determine if the policy should be PCE-Initiated or PCC-Initiated?Q6) For IETF-TE and SR-TE?ThanksRegardsGiorgio
