About This Guide

This guide describes routing protocols including multicast, RIP, OSPF, IS-IS, BGP, and route policies provided by the router and presents configuration and implementation examples.

This document is organized into functional chapters and provides concepts and descriptions of the implementation flow, as well as Command Line Interface (CLI) syntax and command usage.

Unless otherwise specified, the topics and commands described in this document apply to the:

7450 ESS applicability statements refer to the 7450 ESS when it is not running in mixed mode. 7750 SR applicability statements refer to the 7750 SR-7/12, 7750 SR-12e, 7750 SR-a4/a8 and 7750 SR-e1/e2/e3 platforms unless otherwise specified.

Command outputs shown in this guide are examples only; actual displays may differ depending on supported functionality and user configuration.

Router Configuration Process

Table 1 lists the tasks necessary to configure RIP, OSPF, and IS-IS, and BGP protocols, and route policies on the 7450 ESS, 7750 SR, and 7950 XRS. This guide is presented in an overall logical configuration flow. Each section describes a software area and provides CLI syntax and command usage to configure parameters for a functional area.
