Overview
This lab introduces Segment Routing (SR) with MPLS dataplane and traffic engineering with a manual SRTE tunnel. The student will use XRv to implement segment routing over the MPLS dataplane. Upon completion of this lab, the student will be able to:\
- Configure segment routing
- Verify segment routing labels
- Steer traffic using SRTE
Scenarios
- Scenario 1: Segment Routing with LDP
- Scenario 2: Segment Routing without LDP
- Scenario 3. Segment Routing Traffic Engineering Configuration
Components
Features
| VIRL | - Virtual environment for building network topologies
- Simulation of networking components
- Capable of running a range of virtual machines (VMs) running Cisco operating systems (IOS-XE, IOS Classic, IOS-XR, and NX-OS)
- Support for third-party VMs
- Capture and analyze network traffic at any node
- Validate configurations prior to physical deployment
|
| Segment Routing | - Segment Routing (SR) enables a unified, end-to-end, policy-aware network architecture from servers in the data center, through the WAN, and up to the aggregation.
- SR is designed for SDN because it seeks the proper balance between distributed intelligence, centralized optimization, and application-based policy creation.
- Other benefits of SR are related to operational simplicity, better scale (the SR policy is in the packet), and better utilization of the installed infrastructure (lower capex)
