MPLS Recap & Introduction to Segment Routing | Networking Tutorial | Part 4

In this video, we take a deep dive into MPLS (Multiprotocol Label Switching) with a complete recap before moving into Segment Routing (SR).

You’ll learn:
🔹 How traditional IP routing works with OSPF and BGP
🔹 Recursive lookup and the concept of next-hop resolution
🔹 What a BGP-free core is and why service providers use it
🔹 How MPLS encapsulates packets and enables push, pop, and swap operations
🔹 The role of LDP, RSVP, and Segment Routing in creating Label Switched Paths (LSPs)
🔹 Key MPLS concepts like implicit null, explicit null, and router alert

This session sets the foundation for Segment Routing (SRv6), helping you understand how MPLS paved the way for modern routing technologies.

📌 Prerequisites:

Knowledge of IGP (OSPF/IS-IS)

Basics of BGP

MPLS fundamentals (LDP, RSVP)

👉 Watch till the end to get a strong understanding of MPLS before we move into Segment Routing in the next module!
