For the transport no , because SR provides the transport. But for the service such as MPLS L2 VPN with Martini , it requires Targeted LDP session between Ingress and Egress PEs. For BGP Based L2 VPN it requires L2 VPN address family to be configured between edge PEs. For EVPN service it requires BGP.
is a senior consulting engineer in the Advanced Services group at Cisco Systems and has been working with MPLS technologies for more than three years. Jeff's focus is the Asia-Pacific theatre where he has provided detailed designs and design consulting for nearly every major service provider MPLS rollout in the region.
Network engineers and administrators need quick, effective education on this technology to efficiently deploy MPLS-enabled VPNs within their networks. With that goal in mind, provides an in-depth discussion particular to Cisco's MPLS architecture. This book covers MPLS theory and configuration, network design issues, and case studies as well as one major MPLS application: MPLS-based VPNs. The MPLS/VPN architecture and all its mechanisms are explained with configuration examples, suggested design and deployment guidelines, and extensive case studies.
Virtual Private Networks (VPNs) have gained popularity in the near past due to their ability to provide enterprises with a secure remote connectivity networking environment. By allowing multiple customers to “share’ network resources based on a Service Level Agreement, service providers can better utilize the avai lable network resources.

Master the latest MPLS VPN solutions to design, deploy, and troubleshoot advanced or large-scale networksThis book is part of the Networking Technology Series from Cisco Press(r), which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
Segment Routing just eliminates removing LDP and RSVP as Transport Mechanism , for the Service LDP and BGP is used to provision MPLS Layer 2 or MPLS Layer 3 VPNs. Segment Routing still requires LDP or BGP for the MPLS VPN service.
Multiprotocol Label Switching (MPLS) is an innovative technique for high-performance packet forwarding. There are many uses for this new technology, both within a service-provider environment and within the enterprise network, and the most widely deployed usage today is the enabling of Virtual Private Networks (VPNs). With the introduction of MPLS-enabled VPNs, network designers are able to better scale their networks than with the methods available in the past.
, CCIP Edition provides an in-depth discussion particular to Cisco's MPLS architecture and contains all the information necessary to complete the MPLS elective portion of the CCIP certification. This book covers MPLS theory and configuration, network design issues, and case studies as well as one major MPLS application: MPLS-based VPNs. The MPLS/VPN architecture and all of its mechanisms are explained with configuration examples, suggested design and deployment guidelines, and extensive case studies.
If you are not familiar with Segment Routing at all, I suggest you to read my post now. If you are okay with the basics, please continue reading.
So, overall the main reason of this post is, with SR , we just remove the LDP or RSVP requirement for MPLS Transport, but LDP can be used for L2 VPN services and infant have been used by many organizations for decades, and it can still be used.
