2 Executive Summary SDN (Software-defined Network), an emerging architecture which decouples the network control-plane and data-plane, provides an ideal solution for today s network services and applications which are demanding high-bandwidth, dynamic updates and low costs. SDN logically centralizes the network intelligence, let the network administrator programmatically configure and optimize network resource dynamically. Segment routing (SR) is a concept that s been working its way through the IETF standards process but is finally becoming ready for real world deployment. It s a network technology that provides enhanced packet forwarding behavior while minimizing the need for maintaining awareness of mass volumes of network state. This document provides an overview of Segment Routing for IS-IS and OSPFv2 extensions and describes how Spirent TestCenter is used to validate customers related products. Several use cases are given and step-by-step instructions on using Spirent TestCenter to configure and run these test cases are described in detail. The target audiences of this document are who need to use Spirent TestCenter to test products like system test, integration test and product development engineers. Overview of Segment Routing Segment Routing (SR) leverages the source routing and tunneling paradigms. It allows for a flexible definition of end-to-end paths within topologies by encoding paths as sequences of topological sub-paths, called segments. A segment can represent any instruction, topological or service-based. These segments can be advertised by OSPF or IS-IS protocol. The advertised segments are finally translated to MPLS labels, and the data packets are forwarded by label switching. For example, in the following topology, every router is assigned a unique Node-SID value. The IGP metric of the link between Router 2 and Router 3 is 10, and that between Router 2 and Router 4 is 15. The first packet send from Router 1 to has label 99, and 99 is the Node-SID of Every router on the shortest path will swap the labels till it reaches the destination. The packet chooses the link between R2 and R3 instead of R2 and R4 because it is on the shortest path. If you want the packet choose a specific path, for example, through Router 4, the packet should has the label of 99 and spirent.com
3 The following aspects need to be validated for a DUT. 1. After receiving the routes with SR information, which are sub TLVs of extended LSA for OSPF or LSP for IS-IS, DUT should form correct MPLS forwarding table. Complex topology configuration needs effort to configure routes, node SID, prefix SID, adjacency SID, SR capability etc. and error-prone. 2. Need to validate if the packet is forwarded on the expected path. 3. Need to validate it in multi-protocol scenario, such as VPN. 4. Performance test. Using Spirent TestCenter with Segment Routing Spirent TestCenter supports IS-IS and OSPFv2 Segment Routing extensions. And it now supports the following testing with segment routing: Device Wizard and LSA/LSP Generator Wizards L2VPN and L3VPN Wizards NextHop Lookup BGP short-cut IS-IS Mapping Server Automatic Segment Routing Label Management Spirent TestCenter provides LSA/LSP Generator Wizard to generate large scale routes and complex topology. The corresponding sub-tlvs are inserted to the proper position of the LSA/LSPs and proper SIDs are auto configured. The wizard saves customer s configuration effort and eliminates the possibility of misconfiguration. Besides the wizard, user also has the ability to create and fine tune every single sub TLV. Spirent TestCenter uses a simple and intuitive way to validate SR function. Usually a stream is created with source and destination configured, and then the protocol used to resolve the labels is specified. After the routes are exchanged, the stream should be resolved, and the packets with correct labels should be captured from the destination Spirent TestCenter port. This validation can be executed manually or automated by a few commands. Four test cases are included in the doc to help user learning Spirent TestCenter Segment Routing: 1. IS-IS Segment Routing Basis 2. IS-IS Segment Routing for L3VPN 3. OSPFv2 Segment Routing Basic 4. OSPFv2 Segment Routing Explicit Path spirent.com 3
