Getting started
About this guide
This guide describes Layer 2 service and EVPN functionality provided by the SR-series routers and presents examples to configure and implement various protocols and services.
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.
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 the 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.
- 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)

Precautionary and information messages
The following information symbols are used in the documentation.
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.
- This is one substep.
- This is another substep.
