Introduction

This chapter describes the integrated Intermediate System to Intermediate System
(IS-IS) commands used with the BSR 64000™. The Intermediate System to
Intermediate System (IS-IS) is a link state based intra-domain routing protocol used to
build a complete and consistent picture of a network's topology by sharing link state
information across all network Intermediate System (IS) devices. IS-IS is based on an
SPF routing algorithm and shares all the advantages common to other link-state
protocols. It also routes both IP packets and pure OSI packets with no extra
encapsulation by design. IS-IS supports type of service (TOS) identifiers, IP
subnetting, variable subnet masks, external routing, and authentication.
