Step 6: Perform Initial Software Configuration

This procedure connects the router to the network but does not enable it to forward traffic. For complete information about configuring the router to forward traffic, including examples, see the Junos OS configuration guides.

To configure the software:

Enter Configuration Mode

  1. Verify that the router is powered on.
  2. Log in as the “root” user. There is no password.
  3. Start the CLI.
  4. Enter configuration mode.

Configure User Accounts and Passwords

For information about using an encrypted password or an SSH public key string (DSA or RSA), see Configuring the Root Password and user.

  1. Add a password to the root administration user account. Enter a cleartext password.
  2. Create a management console user account.
  3. Set the user account class to super-user.

Configure System Attributes

  1. Configure the name of the router. If the name includes spaces, enclose the name in quotation marks (“ ”).
  2. Configure the router’s domain name.
  3. Configure the IP address and prefix length for the router’s Ethernet interface.
  4. Configure the IP address of a backup router, which is used only while the routing protocol is not running.
  5. Configure the IP address of a DNS server.
  6. (Optional) Configure the static routes to remote subnets with access to the management port. Access to the management port is limited to the local subnet. To access the management port from a remote subnet, you need to add a static route to that subnet within the routing table. For more information about static routes, see the Junos OS Administration Library for Routing Devices.
  7. Configure the telnet service at the [edit system services] hierarchy level.

Commit the Configuration

  1. (Optional) Display the configuration to verify that it is correct.
  2. Commit the configuration to activate it on the router.
  3. (Optional) Configure additional properties by adding the necessary configuration statements. Then commit the changes to activate them on the router.
  4. When you have finished configuring the router, exit configuration mode.
