MikroTik VRRP Configuration with DHCP Server
MikroTik VRRP (Virtual Router Redundancy Protocol) ensures high available 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 my previous article, I discussed how to configure MikroTik VRRP to establish a high available internet network. But most of the office network as well as ISP network use DHCP Server to assign their device IP automatically. So, in this article I will show how to configure MikroTik VRRP with active and backup DHCP Server. Network Diagram To configure VRRP network with MikroTik DHCP Server, 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 other cause, [...]
