The purpose of this lab is to provide a hands-on lab environment that can be used to gain familiarity with Segment Routing (SR) and to demonstrate the concepts. The lab scenarios are based on Cisco’s Metro Fabric Architecture.
This architecture is designed for SP Metro Network (Access, Aggregation) and Mobile Backhauling and is built on top of the successful Cisco Evolved Programmable Network (EPN 5.0) architecture. The design is an evolution of the existing Unified MPLS Architecture and simplifies the transport by employing network programmability using Segment Routing and the SR-PCE or XTC. It simplifies service deployment with end-to-end automated service provisioning using NSO.
The configuration exercises include:

The configuration exercises include:
- L3VPN configuration triggers with ODN SR policies
- SR ODN policies using the SR-PCE controller
- Implementing VRFs with Traffic Engineering using explicit paths with manually configured SIDs
- Deploying the VRFs using an NSO L3VPN service policy
The lab is targeted at network engineers who have a novice to expert level of experience with IGP protocols, MPLS, Segment Routing (SR), BGP and the IOS-XR command line. The more experienced user will gain the most from the lab as it involves hands-on IOS-XR CLI access with the ability to execute additional show commands and make changes to the configuration.
