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

Hello everyone, in this video I am going to install mikrotik router os on hyper-v and after that I will be configure routerOS to provide internet access for clients by configuring dhcp server , create a nat rule , setup pptp vpn server. Ok lets start

1. Hardware Requirements:
   • MikroTik router device (such as a MikroTik RouterBOARD)
   • Ethernet cables
   • Computer with an Ethernet port
   • Power source for the router
2. Initial Setup:
   • Connect the MikroTik router to a power source and to your computer using an Ethernet cable. The router usually has a default IP address for the initial configuration, such as 192.168.88.1. Ensure that your computer is set to obtain an IP address automatically through DHCP.
3. Access the Router:
   • Open a web browser on your computer and enter the default IP address of the MikroTik router in the address bar (e.g., http://192.168.88.1).
   • You should see the MikroTik login page. The default username is “admin,” and there is no password by default. It is crucial to change the default password during the initial setup for security reasons.
4. Basic Configuration:
   • Once logged in, you can start configuring the router. Here are some basic configurations:
     • Set a strong password for the “admin” user.
     • Set the router’s hostname.
     • Configure the time zone.
     • Set the DNS servers.
5. LAN Configuration:
   • Configure the LAN (Local Area Network) settings, including the IP address and subnet mask for the router’s LAN interface.
   • You can create DHCP server pools to assign IP addresses to devices on your local network automatically.
6. WAN Configuration:
   • Configure the WAN (Wide Area Network) interface, which could be connected to your internet service provider (ISP). This often involves configuring the IP address, subnet mask, gateway, and DNS servers provided by your ISP.
   • Set up NAT (Network Address Translation) if you have multiple devices on your LAN and want them to share a single public IP address.
7. Firewall Configuration:
   • Create firewall rules to control incoming and outgoing traffic. MikroTik routers have a powerful firewall system that allows you to filter and control traffic based on various criteria.
8. Security and Access Control:
   • Configure access control lists (ACLs) to restrict or allow specific traffic.
   • Enable SSH or secure Winbox access for remote management and disable insecure services like Telnet.
9. Additional Features:
   • Depending on your needs, you can configure various additional features such as VPNs, VLANs, QoS (Quality of Service), routing protocols, and more.
10. Save and Backup Configuration:
    • After configuring your MikroTik router, make sure to save your configuration settings and create regular backups. This can be done through the router’s web interface.
11. Testing:
    • Test your network to ensure everything is working as expected. Check internet connectivity, LAN connectivity, and any specific services or features you’ve configured.
12. Documentation:
    • Keep thorough documentation of your MikroTik router’s configuration, including any changes you make over time. This will be helpful for troubleshooting and future reference.
