Overview

This lab explores scenarios in enterprise networking where segment routing (SR) is deployed over remote sites connected using Generic Routing Encapsulation (GRE) tunnels. This lab demonstrates how Segment Routing Traffic Engineering (SR-TE) can be carried over GRE tunnel with IPsec. This lab also illustrates implementation of SR-TE over GRE tunnels and IPsec with Class Base Traffic Steering (CBTS). CBTS is used to forward traffic from one remote site to the other either through a local SR network or through an Internet provider cloud. This lab requires familiarity with basic networking architecture and routing fundamentals.
