B5G (5G and beyond) networks are bringing numerous innovation possibilities that are challenging the statu-quo on the way Internet Service Providers' IP backbone networks are managed. Traditional CLI, per box, per supplier and per technology service provisioning methods are not adapted to new business requirements driven by a post severe-pandemic digital adoption and transformation. As a matter of fact, an effective IP service provisioning should be RFT (right-first time) at no time cost. We address this point (of and ever-increasing demands and requirements on backbones) by combining the programmability capability brought by Software Designed Networks and the automation from DevOps tools into an Interactive MPLS Provisioning Management System for SDN(IM-PMS-SDN). The system aims to bring new features on the Management plan Southbound Interface (MPSI) so MPLS service provisioning can be built in an interactive way between Gitlab, Ansible and the underlying Network Infrastructure; The end goal, presented in the experimental results, is to reduce to few minutes an end-to-end B2B service provisioning from prerequisite identification to acceptance tests.
