Juniper Networks M160 manual Configuring the Junos Internet Software

Connecting the Router and Performing Initial Configuration

Configuring the JUNOS Internet Software

The router is shipped with the JUNOS Internet software preinstalled and ready to be configured when the router is powered on. There are three copies of the software: one on a nonrotating flash drive in the Routing Engine, one on a rotating hard drive in the Routing Engine, and one on a PC card that can be inserted into the slot in the Routing Engine faceplate.

When the router boots, it first attempts to start the image on the PC card. If

a PC card is not inserted into the Routing Engine or the attempt otherwise fails, the router next tries the flash drive, and finally the hard drive.

You configure the router by issuing JUNOS command-line interface (CLI) commands, either on a console device attached to the CONSOLE port on the CIP, or over a telnet connection to a network connected to the ETHERNET port on the CIP.

Gather the following information before configuring the router:

Name the router will use on the network

Domain name the router will use

IP address and prefix length information for the Ethernet interface

IP address of a default router

IP address of a DNS server

Password for the root user

To configure the software, follow this procedure:

1.If the router is not already turned on, power it on as described in “Powering On the Router” on page 119.

2.Log in as the “root” user. There is no password.

3.Start the CLI.

root# cli root@>

4.Enter configuration mode.

cli> configure

[edit]

root@#

5.Configure the name of the router. If the name includes spaces, enclose the name in quotation marks (“ ”).

[edit]

root@# set system host-name host-name
