Getting started

About this guide

This guide describes logical IP routing interfaces, virtual routers, IP and MAC-based filtering, and cflowd support and presents configuration and implementation examples.

This guide 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.

Note: Unless otherwise indicated, CLI commands, contexts, and configuration examples in this guide apply for both the MD-CLI and the classic CLI.

The topics and commands described in this document apply to the:

7450 ESS
7750 SR
7950 XRS
Virtualized Service Router

For a list of unsupported features by platform and chassis, see SR OS R23.x.Rx Software Release Notes, part number 3HE 19269 000 x TQZZA.

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

Note:

The SR OS CLI trees and command descriptions can be found in the following guides:

7450 ESS, 7750 SR, 7950 XRS, and VSR Classic CLI Command Reference Guide
7450 ESS, 7750 SR, 7950 XRS, and VSR Clear, Monitor, Show, and Tools Command Reference Guide (for both MD-CLI and Classic CLI)
7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI Command Reference Guide

Note:

This guide generically covers Release 23.x.Rx content and may contain some content that may be released in later maintenance loads. See SR OS R23.x.Rx Software Release Notes, part number 3HE 19269 000 x TQZZA for information about features supported in each load of the Release 23.x.Rx software.

Router configuration process

Configuration process lists the tasks necessary to configure logical IP routing interfaces, virtual routers, IP and MAC-based filtering, and cflowd.

Each chapter in this book is presented in an overall logical configuration flow. Each section describes a software area and the CLI command usage to configure the functional area.

Router configuration	Configure IP router command options	Configuring IP router command options
	Configure IP router	Configuring an IP router with CLI
	Perform service management	Service management tasks
Protocol configuration	Configure VRRP command options	Basic VRRP configurations
	Configure VRRP	Common configuration tasks
	Configure VRRP policy components	Configuring VRRP policy components
	VRRP configuration management	VRRP configuration management tasks
	Configure IP, MAC, and IP exception filter policies	Common configuration tasks
	Filter management	Filter management tasks
	Configure cflowd	Configuring cflowd with CLI
	Cflowd configuration management	Cflowd configuration management tasks

Conventions

This section describes the general conventions used in this guide.

Precautionary and information messages

The following information symbols are used in the documentation.

DANGER: Danger warns that the described activity or situation may result in serious personal injury or death. An electric shock hazard could exist. Before you begin work on this equipment, be aware of hazards involving electrical circuitry, be familiar with networking environments, and implement accident prevention procedures.

WARNING: Warning indicates that the described activity or situation may, or will, cause equipment damage, serious performance problems, or loss of data.

Caution: Caution indicates that the described activity or situation may reduce your component or system performance.

Note: Note provides additional operational information.

Tip: Tip provides suggestions for use or best practices.

Options or substeps in procedures and sequential workflows

Options in a procedure or a sequential workflow are indicated by a bulleted list. In the following example, at step 1, the user must perform the described action. At step 2, the user must perform one of the listed options to complete the step.

Options in a procedure

User must perform this step.
This step offers three options. User must perform one option to complete this step.
- This is one option.
- This is another option.
- This is yet another option.

Substeps in a procedure or a sequential workflow are indicated by letters. In the following example, at step 1, the user must perform the described action. At step 2, the user must perform two substeps (a. and b.) to complete the step.

Substeps in a procedure

User must perform this step.
User must perform all substeps to complete this action.
1. This is one substep.
2. This is another substep.
