Initially Configuring the MX2010 Router

date_range 09-Mar-21

arrow_backward

arrow_forward

The MX2010 router is shipped with Junos OS preinstalled and ready to be configured when the MX2010 router is powered on. There are three copies of the software: one on a CompactFlash card in the CB-RE, one on the solid-state drive (SSD) in the CB-RE, and one on a USB flash drive that can be inserted into the slot in the CB-RE faceplate (see Figure 1).

Note:

The SSD is internal in the CB-RE and cannot be removed.

When the router boots, it first attempts to start the image on the USB flash drive. If a USB flash drive is not inserted into the CB-RE or the attempt otherwise fails, the router next tries the CompactFlash card, and then the SSD.

You configure the router by issuing Junos OS CLI commands, either on a console device attached to the CONSOLE port on the Routing Engine or over a Telnet connection to a network connected to the MGMT port on the Routing Engine.

Figure 1: USB Flash Drive Port on CB-RE

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

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 OS configuration guides.

To configure the software:

Verify that the router is powered on.
Log in as the root user. There is no password.
Start the CLI.
```
root# cli
root@>
```
Enter configuration mode.
```
cli> configure 
[edit]
root@#
```
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
```

Create a management console user account.

[edit]
root@# set system login user user-name authentication plain-text-password
New password: password
Retype new password: password

Set the user account class to super-user.

content_copy zoom_out_map
[edit]
root@# set system login user user-name class super-user

Configure the router’s domain name.
```
[edit]
root@# set system domain-name domain-name
```
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
```
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 
```
Configure the IP address of a DNS server.
```
[edit]
root@# set system name-server address 
```

Set the root authentication password by entering a plain-text password, an encrypted password, or an SSH public key string (DSA or RSA).

content_copy zoom_out_map
[edit]
root@# set system root-authentication plain-text-password
New password: password 
Retype new password: password 

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

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

content_copy zoom_out_map
[edit]
root@# set system root-authentication ssh-rsa public-key

(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 System Basics Configuration Guide.
```
[edit]
root@# set routing-options static route remote-subnet next-hop destination-IP retain no-readvertise
```
Configure the Telnet service at the [edit system services] hierarchy level.
```
[edit]
root@# set system services telnet 
```

(Optional) Display the configuration to verify that it is correct.

content_copy zoom_out_map
[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;
            }
        }
    }
}

Commit the configuration to activate it on the router.
```
[edit]
root@# commit
```
(Optional) Configure additional properties by adding the necessary configuration statements. Then commit the changes to activate them on the router.
```
[edit]
root@host# commit
```
When you have finished configuring the router, exit configuration mode.
```
[edit]
root@host# exit
root@host>
```

Note:

To reinstall Junos OS, you boot the router from the removable media. Do not insert the removable media during normal operations. The router does not operate normally when it is booted from the removable media.

When the router boots from the storage media (removable media, or CompactFlash card), it expands its search in the /config directory of the ruoter for the following files in the following order: juniper.conf (the main configuration file), rescue.conf (the rescue configuration file), and juniper.conf.1 (the first rollback configuration file). When the search finds the first configuration file that can be loaded properly, the file loads and the search ends. If none of the files can be loaded properly, the router does not function properly. If the router boots from an alternate boot device, Junos OS displays a message indicating this when you log in to the router.
