NANOG Meeting Presentation Abstract

Tutorial: BGP Multihoming Techniques
Meeting:	NANOG32
Date / Time:	2004-10-17 1:30pm - 3:00pm
Room:	Regency Ballroom
Presenters:	Speakers: Philip Smith, Cisco Systems Philip Smith joined Cisco Systems in January 1998. He is a member of the Service Provider Architectures Group of Consulting Engineering, within Corporate Development. His role includes working with many ISPs in the Asia-Pacific region and the rest of the world, specifically in network strategies, design, technology, and operations, as well as helping with network configuration and scaling. Other areas of interest also include Internet routing, Internet protocols, IPv6, and encouraging the growth of the Internet around the world. Prior to joining Cisco, he spent five years at PIPEX (now part of UUNET\'s global ISP business), the UK\'s first commercial Internet Service Provider. He was one of the first engineers working in the UK Internet, and played a fundamental role in building the modern Internet in the UK and Europe. Philip is co-author of Cisco ISP Essentials, published by Cisco Press. He holds a Doctor of Philosophy and has a First Class Honours Degree in Physics. He lives in Brisbane, Australia.
Abstract:	This tutorial introduces service providers to some of the features available in BGP to aid multihoming to the Internet. After an explanation of multihoming and the principles being followed in this tutorial, several examples involving different scenarios will be given. This includes the options available when multihoming to the same ISP (including RFC2270) and to different upstreams. Configurations for modifying inbound and outbound traffic flows are covered. The tutorial concludes with a case study and an examination of the use of BGP communities by several ISPs.
