Initially Configuring the MX104 Router
The MX104 router ships with Junos OS preinstalled and ready to be configured when the
router is powered on. One 8-GB internal NAND Flash memory (da0) acts as the hard
drive. Two USB ports on the front panel accept USB storage devices (usb0 and usb1)
that can also function as alternative boot devices.
When the router boots, it first attempts to start the image on the USB 0 flash memory
device, if present, then attempts to start the image on the USB 1 flash memory device, if
present. If a USB flash memory device is not inserted into either of the two slots on the
Routing Engine, or the attempt otherwise fails, the router next tries the active partition
on the NAND Flash device.
You configure the router by issuing Junos OS command-line interface (CLI) commands,
either on a console device attached to the CONSOLE port on the front panel, or over a
telnet connection to a network connected to the Routing Engine ETHERNET port on the
front panel.
NOTE: For the initial configuration, use a device attached to the CONSOLE
port.
Gather the following information before configuring the router:
•
Name that the router will use on the network
•
Domain name that 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
