This learning path will introduce you to the fundamental concepts of SRv6 uSID with L3VPN over an IPv6 transport. Segment Routing over IPv6 (SRv6) is the successor to SR-MPLS. It natively utilizes the IPv6 data plane to deliver Segment Routing capabilities, simplifying network deployments. SRv6 uses the IPv6 Routing Extension Header to carry multiple IPv6 addresses, including multiple SRv6 SIDs. SRv6 uSID extends this concept by allowing a single 128-bit IPv6 destination address to carry up to six individual SIDs, or MPLS labels. By eliminating the need for MPLS label shims and transporting SRv6 SIDs as IPv6 addresses, any IPv6-capable router can forward an SRv6 packet. This enables the deployment of SRv6 services over any IPv6-enabled infrastructure.

Before a core network can provide advanced services and traffic engineering, it must first establish basic transport connectivity between its nodes. In this course, you will learn how interior routing protocols are used to establish dynamic routing within the core, how MPLS technology is used to enhance packet transport across the underlay, and how Segment Routing is changing the way we think about transport paths. In each module you will watch a brief video describing the underlying technology and then walk through a hands-on lab to dive deeper into the relevant protocols and configurations that make underlay routing work.

In this comprehensive course, you'll learn how to implement Segment Routing Traffic Engineering (SR-TE) in your network, with and without Flex-Algo. This approach utilizes SR-MPLS to optimize network performance, reduce operational complexity, and enhance scalability. Through a combination of videos, articles, and hands-on lab exercises, you'll gain a deep understanding of the Segment Routing architecture and its key components. You'll also learn how to configure and troubleshoot Segment Routing policies and topologies using real-world scenarios and best practices. This course is ideal for network engineers, administrators, and architects seeking to expand their knowledge and skills in networking, particularly in the field of Segment Routing. Basic knowledge of networking technologies is recommended.
