J-series Services Routers provide IP routing, WAN and LAN connectivity, and

management services. Available in several models, Services Routers typically

connect small, branch, or regional offices to a central site, and link Internet service

provider (ISP) networks.

Follow these instructions to initially set up a J-series Services Router. You need no

previous JUNOS Internet software experience, but must have managed a network

and configured other routers. For more information, see the J-series documentation

at http://www.juniper.net/techpubs/.

J-series Services Router Quick Start

2What You Need to Know

What You Need to Know

J-Web Access The Web interface to the router—called the J-Web interface—is enabled by default.

To configure a Services Router with the Web interface, you attach a PC or laptop to

Ethernet management port 0on the chassis. Ethernet management port 0is the

built-in Fast Ethernet PORT 0 (internally named fe-0/0/0).

(See “1. Connecting, Logging In, and Starting the J-Web Interface” on page 5.)

CLI Console Access Services Routers are shipped with a console cable and adapter. To configure a

Services Router through the console port with the JUNOS command-line interface

(CLI), you use a terminal emulation program such as Microsoft Windows

HyperTermimal.

(See “1. Connecting, Logging In, and Starting the CLI” on page 8.)

Required Licenses To use the following features on a Services Router, you must purchase a license.

(See “3. Adding Licenses with the CLI” on page 9 or “3. Adding Licenses with the

J-Web Interface” on page 6.)

Advanced Border Gateway Protocol (BGP) support for route reflectors

Data link switching (DLSw)

J-Flow traffic analysis

Slot Numbers J2300 routers have built-in WAN ports. Other models have slots 1 through 6 for

replaceable Physical Interface Modules (PIMs). On J4300 and J6300 routers, PIM

slots are numbered from left to right, bottom to top.

Interfaces and Ports Interfaces are named by type, slot number, module number (always 0), and port

number. Port numbering starts with 0. For example:

On J2300, J4300, and J6300 routers, the built-in Fast Ethernet LAN PORT 0 and

PORT 1, which are in slot 0, are named fe-0/0/0 and fe-0/0/1.

On models with replaceable PIMs, the first port on a T1 PIM in slot 1 is named

t1-1/0/0.

Management IP

Address A Services Router ships from the factory with the IP address 192.168.1.1/24

assigned to Ethernet management port 0. Because this address is not part of the

configuration, it is deleted when you change the configuration in any way. You must

configure an IP address for this LAN port before any other configuration.

(See “4. Performing Basic Configuration with the CLI” on page 9 or “4. Performing

Basic Configuration with the J-Web Interface” on page 6.)

Remote Access Although Telnet and SSH are both supported, they are disabled by default.

Installing and Connecting Power 3
