Virtual Router Redundancy Protocol (VRRP)

Virtual Router Redundancy Protocol (VRRP) is an open protocol (not a proprietary protocol). It introduces the concept of the virtual router to improve the redundancy of the default gateway of hosts.

This article checks the uses and importance of VRRP.



How Does VRRP Assure Network Redundancy?

According to VRRP, a virtual router (VR) is not just a physical router but includes the master and backup routers.


So, the default gateway of a host is the VR instead of a single physical router.


This VR concept ensures that if one router fails, another will take the charge immediately. However, at a time, only one master acts as the default gateway, and the master informs the backup routers of its current status.

The backup router will take place in the position of the master if the master becomes unavailable.




Can I Use VRRP with HSRP?

Virtual Router Redundancy Protocol is an open-source protocol similar to Cisco's proprietary protocol, the Hot Standby Router Protocol (HSRP). However, both protocols are not compatible despite their similarities.


We cannot use VRRP with HSRP.


You have learned the basics of VRRP. Let us check how to configure the Virtual Router Redundancy Protocol.


VRRP Configurations Tips

  1. The Virtual Router (VR) works as the default gateway of hosts.

  2. A group of physical routers comes under VR, but only one master at a time.

  3. The master router informs backup routers of its current status (all the time).

  4. When the master fails, one backup router assumes the role of master.

  5. The concept of VirtualRuter by Virtual Router Redundancy Protocol improves network redundancy.

  6. The MAC address of the VR must be in this format: 00-00-5E-00-01-XX.

  7. The IP address used for multicast is 224.0.0.18.


You have learned the basics of the Virtual Router Redundancy Protocol and its application in a network.

How to Configure The Internet Connection On Fedora Linux?

Configuring an Internet connection on a Fedora Linux PC is simple. You can use DSL broadband, Cable Internet, and WiFi to give the Internet.

This tutorial explains step-by-step instructions to configure a DSL broadband connection in Fedora Linux.



Can I configure the Internet From GUI?

We can set up the Internet on a Fedora Linux computer from the GUI. We do not need to go to the terminal and execute commands.

So, let us check how to set up a broadband connection on a Fedora Linux PC.




Configure DSL On a Computer Having Fedora Linux


  1. Connect the Modem to the Computer

    1. The first step to setting up the Internet is to connect the LAN port of the modem to the Ethernet port on your Linux PC with an Ethernet cable.

    2. Power on the modem. Wait till the power and Internet (DSL) lights are steady.

  2. Fedora Network Settings

    1. Click the Network icon at the bottom right of the screen.


      You can also reach the network by typing the command system-config-network.


    2. Click on the Manage Connections button.

    3. Click on the Wired Connection. Then click the Edit button.

    4. You can enter the IP address, Default Gateway, and Subnet Mask information provided by your ISP.


      If you do not have these values, contact your Internet Service Provider (ISP).


      If your ISP does not provide a DNS address, you can use the default Google DNS address.


      8.8.8.8 and 8.8.4.4 are the Google DNS IP addresses.


  3. On Older Interfaces

    • Click on the toolbar and select New.

    • It will open a new window, Add new Device Type.

    • Choose DSL connection and click forward.

    • Enter the ISP details like username and password.



How to Check The Internet Connection On Fedora Linux?

To check the Internet connection on Fedora Linux, go to the Network Configuration window.

  • Select new connection window
  • Click on activate
  • Type ping google.com

If you receive a reply, the connection is fine.




How to Disconnect the Internet From Fedora Linux?

Click the Deactivate button from the network configuration to disconnect the Internet.
