NANOG Meeting Presentation Abstract

Tutorial: IP Routing Protocol Scalability: Theory and Examples
Meeting:	NANOG23
Date / Time:	2001-10-21 1:30pm - 3:00pm
Room:	Jewett Ballroom F-H
Presenters:	Speakers: Alvaro Retana, Cisco Systems Alvaro Retana is a Technical Leader in Cisco\'s IP Routing Deployment and Scalability Team, where he works first-hand on advanced features in routing protocols. Alvaro was formerly a technical lead for both the Internet Service Provider Support Team and the Routing Protocols Team at the Cisco Technical Assistance Center in Research Triangle Park, NC.
Abstract:	This tutorial addresses the building blocks of IP routing protocol scalability (hierarchy, redundancy, and addressing and summarization) along with protocol-specific issues. BGP, ISIS and OSPF configurations and parameters are explored. The examples presented include a set of protocol-specific \"best practices.\" Intended Audience: Network operators and engineers with IP routing experience. Knowledge of the protocols covered is expected. Tutorial Outline Introduction - Scope of the Presentation - Agenda Scalability Building Blocks Relationship to Convergence and Stability Impact/Use of Hierarchy/Redundancy/Addressing and Summarization Hierarchy - Why is hierarchy important? - Brief overview of service placement (per layer. Redundancy - When is redundancy too much? - IGP Flooding Addressing and Summarization -Aggregation Methods per protocol ISIS Scalability Hierarchy in ISIS - L or L-only networks - Use and limitations of Hierarchical Networks - Route Leaking Detection and Propagation of Changes - Fast Hellos - LSP Generation - SPF Runs - Exponential Backoff Other tips... - Overload bit OSPF Scalability Hierarchy - Area types and flow of routing information - LSA Filtering Detection and Propagation of Changes - Fast Hellos - LSP Generation - SPF Runs - Exponential Backoff Other tips... - Overload bit OSPF Scalability Hierarchy - Area types and flow of routing information - LSA Filtering Detection and propagation of changes - Fast Hellos - LSA Generation - SPF Runs - Exponential Backoff Other tips... - Stub router advertisement BGP Scalability iBGP Full Mesh - Route Propagation Requirements Peer-Groups - Configuration Grouping and UPDATE Generation Route Reflectors - Deployment (Hierarchy) Confederations - Deployment - Interaction with IGPs Detection and Propagation of Changes - minAdvertisementTimer - NEXT_HOP Reachability - 4.5.3 Route Dampening Summary and Conclusions
