SRv6 - Key Concepts for Engineers

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.

Intro to Segment Routing Lab

MPLS has been around for over two decades and is the cornerstone of Service Provider Networks and many enterprise, utility and federal networks. MPLS delivers mission-critical applications and services. Segment Routing has taken the stage to replace MPLS because it accomplishes the same as MPLS but is less complex, extremely robust and can be scaled without limitations. This lab will introduce you to the basics of Segment Routing.

Core Routing Fundamentals

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.

Deploying IPv6 with ISIS

Organizations have relied on IPv4 for decades, but transitioning from IPv4 to IPv6 is necessary to accommodate the growing number of devices and the increasing demand for IP addresses. Most organizations have exhausted their IPv4 address space. Transitioning to IPv6 allows network engineers to future-proof their networks against the inevitable exhaustion of IPv4 addresses.

MPLS and Segment Routing Briefing

Multiprotocol Label Switching (MPLS) and Segment Routing (SR) technologies are critical to Carrier Networks today, and will continue to become more and more critical into the future. These technologies provide organizations with the ability to transport various types and classifications of traffic across an IP network and to do it with future-facing automation & orchestration. In addition, Segment Routing makes the network far more robust through fast reroute and enhanced traffic engineering capabilities. As new paradigms such as 5G and the Internet-of-Things (IoT) rapidly change the landscape, the importance of MPLS and SR will continue to expand within many industry verticals.
