Steps
Introduction
This chapter describes the AI2524 protocol configuration steps for th
OSPF TCP/IP, IGRP TCP/IP and RIP TCP/IP.

TCP/IP
Configuration
Steps
Open Shortest Path First (OSPF) is an IGP designed expressly for IP
networks. OSPF supports IP subnetting and tagging of externally de-
rived routing information. OSPF also allows packet authentication and
uses IP multicast when sending/receiving packets.
OSPF typically requires coordination among many internal routers,
area border routers (routers connected to multiple areas), and autono-
mous system boundary routers. At a minimum, OSPF-based routers or
access servers can be configured with all default parameter values, no
authentication, and interfaces assigned to areas. If you plan to custom-
ize your environment, ensure coordinated configurations of all routers.
To configure OSPF, complete these tasks. You must enable OSPF; the
other tasks are optional, but might be required for your application.
z Enable OSPF
z Configure OSPF Interface Parameters
z Configure OSPF over Different Physical Networks
z Configure OSPF Area Parameters
z Configure OSPF Not So Stubby Area (NSSA
z Configure Route Summarization between OSPF Areas
z Configure Route Summarization When Redistributing Routes into
OSPF
z Create Virtual Links
z Generate a Default Route
z Configure Lookup of DNS Names
z Force the Router ID Choice with a Loopback Interfac
z Disable Default OSPF Metric Calculation Based on Bandwidth
z Configure OSPF on Simplex Ethernet Interfaces
