Cisco Segment Routing LDP Coexistence Internetworking Lab v1 now available on Cisco dCloud!

[lamarsh]

Overview

This lab requires familiarity with the Cisco® networking architecture and routing fundamentals. This lab explores how to use Segment Routing (SR) in an LDP coexistence-internetworking environment and how to migrate an LDP-based network to an SR-based network.

This demonstration requires familiarity with networking architecture and routing fundamentals. For more information about SR, refer to www.segment-routing.net.

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).
