Hands-On Lab Workshop: SR-MPLS with ISIS for Network Engineers
Join our virtual lab workshop to learn Segment Routing with MPLS (SR-MPLS) using ISIS and Fast Reroute. This session covers SR-MPLS fundamentals, including simplified service deployment via the MPLS data plane and Prefix label advertisement through standard ISIS/OSPF extensions, removing Classical LDP requirements. Participants will configure basic routing and SR-MPLS with ISIS on Cisco routers and set up SR-MPLS over ISIS plus BGP L3VPN/L2VPN on Cisco XRv9000 virtual routers. Live Q&A with experts is included—ideal for Network Engineers interested in transitioning to SR-MPLS networking.
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.
How SR-MPLS Is Changing the Way We Think About IP Networking
Learn how SR-MPLS, or Segment Routing Multiprotocol Label Switching, changes the way we think about traditional IP networking.
Segment Routing Technical Training
Segment Routing is the latest technology that replaces MPLS and is based on source routing. Segment Routing provides complete control over the forwarding path from the source node by encoding the path in the header of the packet. Segment Routing is implemented using extensions to the native IGP routing protocols, it does not require any additional protocols and removes unnecessary protocols simplifying the network. Segment Routing runs natively on an MPLS or IPv6 data plane and can coexist with LDP, making for a painless migration.

SR-MPLS With Flex-Algo Lab
Service providers and other large organizations rely on MPLS on multiple platforms to deliver mission-critical applications and services. Segment Routing is the next-generation technology that replaces MPLS, and here we look at SR-MPLS along with an advanced feature called Flexible Algorithm (Flex-Algo). Segment Routing with Flex-Algo enables the router to assign a user-defined algorithm to the IGP that is implemented dynamically and on-demand.

CNC SR-MPLS Core Networking Guided Lab
This WWT-guided lab demonstrates several aspects of Cisco's Crossword Network Controller (CNC) in conjunction with Cisco NSO, including path control with Cisco SR-PCE (Path Computational Engine). CNC is a Segment Routing SDN Controller for transport networks. CNC allows an operator to create and manage VPN and Transport services with diverse SLAs, such as disjointness, bandwidth awareness, or low latency. It provides for creating engineered transport paths using SR-TE parameters and provisioning and linking VPN services to these paths. CNC performs real-time network optimization based on current network conditions utilizing the Crosswork Optimization Engine in conjunction with Cisco's IOS-XR-based Segment Routing Path Computation Element or SR-PCE. Cisco NSO is also included and tightly coupled to CNC as the Provisioning engine.
SRv6 uSID Flex-Algo Lab
SRv6, a native IPv6 data plane protocol, offers Segment Routing capabilities that significantly simplify network deployments. It employs source routing by encoding the path in the packet header. SRv6 utilizes the IPv6 Routing Extension Header to carry multiple IPv6 addresses, including multiple SRv6 SIDs. SRv6 uSID takes this concept further by allowing a single 128-bit IPv6 destination address to carry up to six individual uSIDs, or labels, in MPLS terms. In this lab, we will explore the use of Flexible Algorithm (FA) with SRv6 uSID and BGP L3VPN.

SRv6 uSID Lab
SRv6 utilizes the IPv6 data plane natively to deliver Segment Routing capabilities which dramatically simplifies network deployments. 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 means that you can run SRv6 services over any IPv6-enabled infrastructure. This lab will introduce you to the basics of SRv6 with L3VPN over a purely IPv6 transport.
IP Routing Lab for Optical Engineers
There is a movement in the industry to combine the optical network and the routed network, with Cisco leading the charge. The architecture is known as RON, Routed Optical Networks. With the RON architecture, the services that Optical Engineers are accustomed to delivering within the optical network are now provided via the routed network. Services such as site-to-site traffic demand, path selection, and path protection. With this shift in architecture, there is a growing requirement for optical engineers' expertise to span both optical and routing. This lab is designed to demonstrate how the routed network delivers these services and how to configure a basic RON network using Segment Routing.
