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

  • VIRL
  • IOS XRv
  • Anyconnect

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)
