OSPF

BLADEOS supports the Open Shortest Path First (OSPF) routing protocol. The BLADEOS implementation conforms to the OSPF version 2 specifications detailed in Internet RFC 1583, and OSPF version 3 specifications in RFC 2740. The following sections discuss OSPF support for the RackSwitch G8124:

￿“OSPFv2 Overview” on page 273. This section provides information on OSPFv2 concepts, such as types of OSPF areas, types of routing devices, neighbors, adjacencies, link state database, authentication, and internal versus external routing.

￿“OSPFv2 Implementation in BLADEOS” on page 278. This section describes how OSPFv2 is implemented in BLADEOS, such as configuration parameters, electing the designated router, summarizing routes, defining route maps and so forth.

￿“OSPFv2 Configuration Examples” on page 288. This section provides step-by-step instructions on configuring different OSPFv2 examples:

￿Creating a simple OSPF domain

￿Creating virtual links

￿Summarizing routes

￿“OSPFv3 Implementation in BLADEOS” on page 298. This section describes differences and additional features found in OSPFv3.

OSPFv2 Overview

OSPF is designed for routing traffic within a single IP domain called an Autonomous System (AS). The AS can be divided into smaller logical units known as areas.

All routing devices maintain link information in their own Link State Database (LSDB). The LSDB for all routing devices within an area is identical but is not exchanged between different areas. Only routing updates are exchanged between areas, thereby significantly reducing the overhead for maintaining routing information on a large, dynamic network.

The following sections describe key OSPF concepts.
