What is Segment Routing?
Segment routing is an innovative source-based routing approach that has been implemented as a means to simplify traffic management by allowing an efficient path selection. Unlike other traditional routing techniques, SR does not require complicated protocols to guide the forwarding process; it instead employs segments in which each segment symbolizes a particular forwarding direction.
Thus, segment routing increases scalability, flexibility, and efficiency using the strengths of current protocols such as MPLS and integrating with SDN.
Segment routing allows for effective traffic engineering, quick rerouting, and streamlined network operations, making it essential for modern network architectures and an integral part of Cisco IOS XR training.
Prerequisites for Segment Routing Training
- Familiarity with Cisco Internetwork Operating System (IOS®) XR software
- Knowledge of general networking concepts
Why choose Segment Routing Training?
SR’s core purpose is to simplify the network and, side-by-side, reduce resource utilization. With this, it will be easier to manage as well as operate your network. Apart from this, SR can be useful in cases such as:
- Segment Routing (SR) transforms complex network operations into a straightforward, efficient process.
- By streamlining operations, SR helps reduce hardware and management costs.
- Segment routing gracefully integrates into various architectures, whether you are using MPLS or IPv6.
- With SR, you can craft traffic flows on-demand. Optimize paths based on current conditions and magically reduce congestion and latency.
- As your business grows, so do the demands on your network. SR aligns with your needs, enabling you to scale up without the multiple headaches.
- SR simplifies routing logic, reducing the risk of misconfigurations while dynamically adjusting traffic routes to enhance reliability.

Frequently Asked Questions
Q1. What is Segment Routing?
Segment Routing (SR) is a modern routing architecture that simplifies network traffic engineering by encoding paths into packets as a series of segments. These segments represent forwarding instructions that guide packets through the network without requiring per-flow state in intermediate routers. It enhances scalability, flexibility, and traffic optimization in IP and MPLS networks.
Q2. Is Segment Routing the Same as MPLS?
No, Segment Routing is not the same as MPLS, but it can be seen as an evolution of MPLS. While both use labels for forwarding, MPLS relies on Label Distribution Protocol (LDP) or Resource Reservation Protocol-Traffic Engineering (RSVP-TE) for label management, whereas Segment Routing eliminates the need for these protocols by using distributed control via IGP (such as IS-IS or OSPF) and segment identifiers (SIDs).
Q3. Who should take this Segment Routing training?
This training is ideal for network engineers, service providers, and IT professionals who want to learn about modern traffic engineering, MPLS evolution, and software-defined networking (SDN) concepts.
Q4. What are the prerequisites for this course?
A basic understanding of networking concepts, MPLS, and routing protocols (such as OSPF or IS-IS) is recommended. Prior knowledge of IP/MPLS networks will be helpful but is not mandatory.
Q5. Will there be hands-on lab exercises in this training?
Yes, our segment routing course includes practical labs where you will configure and troubleshoot Segment Routing on network devices using real-world scenarios.
Q6. What certification does the segment routing training prepare me for?
This course helps prepare for Cisco’s Segment Routing (SR) topics covered in advanced certifications like CCNP Service Provider, CCIE Service Provider, and Cisco SD-WAN certifications.
Q7. Will I receive a certificate after completing the training?
Yes, upon successful completion, you will receive a Segment Routing Training Certificate from PyNet Labs.
