Step 8: Perform Initial Software Configuration

This procedure connects the router to the network but does not enable it to forward traffic. For complete information about enabling the router to forward traffic, including examples, see the JUNOS Internet software configuration guides.

To configure the software, follow this procedure:

1. Verify that the router is powered on as described in 7: Power On the Router.
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
6. Configure the router's domain name.
   [edit]
   root@# set system domain-name domain-name
7. Configure the IP address and prefix length for the router's Ethernet interface.
   [edit]
   root@# set interfaces fxp0 unit 0 family inet address address/prefix-length
8. Configure the IP address of a backup router, which is used only while the routing protocol is not running.
   [edit]
   root@# set system backup-router address
9. Configure the IP address of a DNS server.
   [edit]
   root@# set system name-server address
10. Set the root authentication password by entering either a clear-text password, an encrypted password, or an SSH public key string (DSA or RSA).
    [edit]
    root@# set system root-authentication plain-text-password
    New password: password
    Retype new password: password

    or

    [edit]
    root@# set system root-authentication encrypted-password encrypted-password

    or

    [edit]
    root@# set system root-authentication ssh-dsa public-key

    or

    [edit]
    root@# set system root-authentication ssh-rsa public-key
11. Optionally, display the configuration to verify that it is correct.
    [edit]
    root@# show

    system {

    host-name host-name;

    domain-name domain-name;

    backup-router address;

    root-authentication {

    authentication-method (password | public-key);

    }

    name-server {

    address;

    }

    }

    interfaces {

    fxp0 {

    unit 0 {

    family inet {

    address address/prefix-length;

    }

    }

    }

    }

12. Commit the configuration to activate it on the router.
    [edit]
    root@# commit
13. Optionally, configure additional properties by adding the necessary configuration statements. Then commit the changes to activate them on the router.
    [edit]
    root@host# commit
14. When you have finished configuring the router, exit configuration mode.
    [edit]
    root@host# exit
    root@host>
