ISIS2 Lab Scenario: Two-Level ISIS Routing Domain

Abstract

This scenario presents a two-level ISIS routing domain and introduces a number of configuration elements common to service provider networks. Specifically, the elements necessary to build a functional and scalable network topology, including route summarization, LSP flood scoping, route leaking, and redistribution, are explored from a configuration perspective.
