Overview of Services Routers

J-series Services Routers provide stable, reliable, and efficient IP routing, WAN and LAN connectivity, and management services for small to medium-sized enterprise networks. Services Routers typically connect small, branch, or regional offices to a central site router, and link Internet service provider (ISP) networks.

All J-series Services Routers run the JUNOS software, which offers many advanced routing and security services. For more information about software features, see J-series Software Features and Licenses. A single, common JUNOS code base simplifies deployment, patches, and software upgrades.

You can use two user interfaces to monitor, configure, troubleshoot, and manage a Services Router:

• J-Web interface—A Web-based graphical interface that allows you to operate a router without commands. The J-Web interface provides access to all JUNOS functionality and features. Quick Configuration wizards simplify basic configuration and minimize the risk of operator error.
• JUNOS command-line interface—A Juniper Networks command shell that runs on top of a UNIX-based operating system kernel. The CLI is a straightforward command interface. On a single line, you type commands that are executed when you press the Enter key. The CLI provides command Help and command completion.

For an introduction to the J-Web and CLI interfaces, see Services Router User Interface Overview. For more information, see the J-Web Interface User Guide and the JUNOS CLI User Guide.
