VyOS Installation and Configuration Guide

Introduction

VyOS is an open-source network operating system based on Debian GNU/Linux that provides software-based network routing, firewall, and VPN functionality. This guide covers the installation and configuration of VyOS, including setting up OSPF.

Installation of VyOS

1. Download VyOS ISO:

   – Go to the VyOS download page and download the ISO image of the latest stable version.

2. Create a Bootable USB Drive:

   – For Windows: Use Rufus to create a bootable USB drive.

   – For Linux/macOS: Use the `dd` command.

3. Boot from the USB Drive:

   – Insert the USB drive into your server or PC and boot from it. You may need to change the boot order in the BIOS/UEFI settings.

4. Install VyOS:

   – Once booted, you will be presented with the VyOS live environment. Log in with the default credentials:

     Username: vyos
     Password: vyos

   – To start the installation, enter:

     install image

   – Follow the prompts to select the installation disk, partitioning scheme, and other options. You will also set a password for the `vyos` user and create a GRUB bootloader.

5. Reboot:

   – After the installation completes, reboot the system and remove the USB drive. The system will boot into the installed VyOS.

Basic Configuration of VyOS

1. Log In:

   – Log in with the user `vyos` and the password you set during installation.

2. Enter Configuration Mode:

   configure

3. Set Hostname:

   set system host-name my-router
   commit
   save

4. Configure Network Interfaces:

   – Identify the network interfaces using the `show interfaces` command.

   – Configure an interface (e.g., `eth0`) with a static IP address:

     set interfaces ethernet eth0 address ‘192.168.1.1/24’
     commit
     save

5. Configure Default Gateway:

   set protocols static route 0.0.0.0/0 next-hop 192.168.1.254
   commit
   save

6. Set DNS Servers:

   set system name-server 8.8.8.8
   set system name-server 8.8.4.4
   commit
   save

7. Enable SSH:

   set service ssh port 22
   commit
   save

Configuring OSPF

Enable OSPF

To configure OSPF (Open Shortest Path First) on VyOS:

1. Enter Configuration Mode:

   configure

2. Enable OSPF:

   set protocols ospf parameters router-id 1.1.1.1

   Replace `1.1.1.1` with a unique router ID for the OSPF instance.

Configure OSPF on Interfaces

Specify which interfaces will participate in OSPF and their respective areas:

   set protocols ospf area 0 network 192.168.1.0/24
   set protocols ospf area 0 network 192.168.2.0/24

   Replace `192.168.1.0/24` and `192.168.2.0/24` with the actual network addresses of your interfaces.

Adjust OSPF Interface Parameters (Optional)

You can adjust OSPF interface parameters like cost, hello interval, and dead interval:

   set interfaces ethernet eth0 ip ospf cost 10
   set interfaces ethernet eth0 ip ospf hello-interval 10
   set interfaces ethernet eth0 ip ospf dead-interval 40

   Replace `eth0` with your actual interface name.

Commit and Save the Configuration

   commit
   save

Example Configuration for OSPF

Here is an example configuration where two interfaces (`eth0` and `eth1`) participate in OSPF with different network segments.

Configuration for Router 1:

configure
set interfaces ethernet eth0 address ‘192.168.1.1/24’
set interfaces ethernet eth1 address ‘10.1.1.1/24’

set protocols ospf parameters router-id 1.1.1.1
set protocols ospf area 0 network 192.168.1.0/24
set protocols ospf area 0 network 10.1.1.0/24

commit
save

Configuration for Router 2:

configure
set interfaces ethernet eth0 address ‘192.168.1.2/24’
set interfaces ethernet eth1 address ‘10.1.2.1/24’

set protocols ospf parameters router-id 2.2.2.2
set protocols ospf area 0 network 192.168.1.0/24
set protocols ospf area 0 network 10.1.2.0/24

commit
save

Verifying OSPF Configuration

1. Check OSPF Neighbors:

   show ip ospf neighbor

2. Check OSPF Routes:

   show ip route ospf

3. Check OSPF Interface Status:

   show ip ospf interface

Additional OSPF Configurations

Configuring OSPF Authentication

To enhance security, you can configure OSPF authentication on the interfaces:

1. Set Authentication Type and Key:

   set interfaces ethernet eth0 ip ospf authentication message-digest
   set interfaces ethernet eth0 ip ospf message-digest-key 1 md5 ‘yourpassword’

   Replace `yourpassword` with a secure password.

2. Configure OSPF Area Authentication:

   set protocols ospf area 0 authentication message-digest

Configuring OSPF Redistribution

To redistribute routes from other protocols (e.g., BGP) into OSPF:

1. Set Redistribution:

   set protocols ospf redistribute bgp
   commit
   save

Troubleshooting OSPF

1. Check OSPF Process:

   show ip ospf

2. Check OSPF Logs:

   show log

3. Debug OSPF:

   monitor protocol ospf

Hi everyone , you can download Cisco Router ISO file from here and install on your GNS3 or EVE-NG platforms

Download Cisco C7200

1. Prepare the Windows ISO: Obtain a Windows installation ISO file. You can download these from the Microsoft website or use an existing ISO file you have.
2. Upload the ISO to EVE-NG: Log in to the EVE-NG web interface. In the top menu, go to “Images” and then click on “Browse” to select the Windows ISO file from your local machine. Click on “Upload” to upload the ISO file to EVE-NG.
3. Create a QEMU VM: In the EVE-NG web interface, go to the “Node” section and click on “Add Node.” Select the type as “QEMU” and configure the settings for the VM. You can specify the number of CPUs, amount of RAM, and the size of the hard disk.
4. Map the Windows ISO: In the QEMU VM settings, go to the “Console” tab. Under the “CD/DVD” section, select the Windows ISO file you uploaded earlier as the CD/DVD image.
5. Start the VM: After configuring the VM settings, click on “Add Node” to create the QEMU VM. Start the VM by clicking on the play button in the EVE-NG interface.
6. Install Windows: Access the VM console by right-clicking on the VM in the EVE-NG interface and selecting “Console.” The VM will boot from the Windows ISO. Follow the on-screen instructions to install Windows. You may need to format the virtual hard disk and select the installation partition during the process.
7. Complete the Installation: After Windows is installed, the VM will restart. You can then log in to Windows and configure it as needed.
8. Optional: Install VirtIO Drivers: For better performance, you can install VirtIO drivers in Windows. These drivers are included in the EVE-NG installation and can be found in the /opt/unetlab/addons/qemu/virtio-win directory. To install the drivers, mount the VirtIO ISO in Windows and run the installer.
9. Access Windows from EVE-NG: Once Windows is installed and running, you can access it from EVE-NG by right-clicking on the VM in the EVE-NG interface and selecting “Console.”
10. Activate Windows: After installation, you’ll need to activate Windows using a valid product key. You can do this by going to “Settings” > “Update & Security” > “Activation” in Windows.

Remember to comply with Microsoft’s licensing terms and ensure that you have a valid license for Windows when using it on EVE-NG or any other virtualization platform.
