  • MikroTik Hardware Redundancy with VRRP

    MikroTik VRRP (Virtual Router Redundancy Protocol) ensures high availability internet network. If any organization requires uninterrupted internet connection, MikroTik VRRP implementation will be a vital solution for them. MikroTik VRRP creates a virtual router accumulating two or more physical routers and ensures uninterrupted internet connection keeping activate one physical router always. That means, if any physical router fails to operate due to any hardware failure, MikroTik VRRP uses another backup router for internet gateway until the running router comes back again. In this article, I will discuss how to configure MikroTik VRRP to establish a high available internet network. Network Diagram To configure VRRP in MikroTik Router, I am following a network diagram like the below image. In this network, two MikroTik RouterOS (Master_RouterOS and Backup_RouterOS) are the member of a MikroTik VRRP. So, when both routers are up and running, network traffic will pass through Master_RouterOS. If Master_RouterOS fails to operate due to hardware failure or any cause, Backup_RouterOS will turn into Master Router and pass network traffic until the Master_RouterOS comes back again. When the Master_RouterOS recovers again, it turns into Master Router and Backup_RouterOS will turn into Back Router. So, a hardware redundancy network will be ensured [...]
