SSR Software Installation Guide

Introduction​

Welcome to Session Smart Routing - the first software-based routing solution designed to be both session-oriented and service-centric through the application of Secure Vector Routing. The purpose of this guide is to provide an overview and installation walkthrough for the SSR Router and Conductor products into a Linux operating system environment. This product suite is collectively known as SSR Software.

Before You Begin​

Before you begin the installation and configuration of an SSR Networking Plaform, you must:

  • Be familiar with Linux fundamentals, basic network addressing, and IP networking terminology.
  • Be a system administrator to perform the installation and configuration.
  • Have an entry in /etc/sudoers allowing you to execute Linux shell commands as root (via sudo). Failure to do so may result in the loss of remote management connectivity to the router.
note

The examples listed in this guide generally prefer running commands as a non-root user, except as noted, and prepend commands that must be run as a superuser with sudo. The SSH Root login is not permitted.

Installation Process​

Beginning with SSR 6.3.0, a universal image-based SSR ISO is provided to simplify and streamline the SSR installation and initialization process. This version supports Conductor-managed image-based installations as well as Mist-managed deployments.

Installation to your device utilizes the SSR ISO, downloaded as a bootable image to a USB drive or from disk. The install process is as follows:

A Mist-redirect ZTP process for Conductor-managed deployments is supported on Juniper branded hardware devices - the SSR1x0/1x00. See Onboard an SSR Device to a Conductor for details about this process.

Upgrades​

Please refer to Upgrade Considerations before upgrading. Additional prerequisites include configuring a user with super user (sudo) privileges. The SSH Root login is not permitted. If the existing version allows SSH Root login, it will be disabled during the upgrade. When a system is installed using the OTP ISO, a "t128" user is configured with sudo privileges.

For full details and instructions refer to Upgrading the SSR Networking Platform.

Version Dependencies​

The conductor major.minor version must be greater than or equal to the router version. The router version can not exceed the conductors major.minor version, but it can have a greater patch version. All versions currently under support can be run on a router and managed by the conductor, provided that the conductor version is greater. Versions of software not under support may work, but are not guaranteed to do so.
