OSPF Commands

Introduction

This chapter describes the Open Shortest Path First (OSPF) commands used with the
BSR 64000™.
OSPF is a link-state routing protocol that runs internally to a single Autonomous
System, such as an enterprise network. At the core of the OSPF protocol is a
distributed, replicated link-state database.
OSPF specifies a Link-state Advertisements (LSAs) that allow OSPF routers to
update each other about the LAN and WAN links to which they connected. OSPF
ensures that each OSPF router has an identical link-state database, except during
period of convergence. Using the link-state database, each OSPF router calculates its
IP routing table with the best routes through the network.
