MikroTik Router Configuration High Availability With VRRP And HSRP

Have you ever heard of MikroTik hardware redundancy with VRRP? It's a powerful networking technique that allows you to achieve high availability and robustness in your network infrastructure. By using VRRP, you can ensure that your network continues to function even if one of your MikroTik routers fails. In this post, we'll go into more detail about what VRRP is, how it works, and how you can set it up.

What is VRRP?

VRRP stands for Virtual Router Redundancy Protocol. It's a protocol that enables a group of routers to act as a single virtual router. The virtual router has a virtual IP address, which is shared by all the routers in the group. The routers in the group communicate with each other using VRRP messages to elect one router as the active router and the others as standby routers. The active router is responsible for forwarding packets sent to the virtual IP address, while the standby routers monitor the active router and take over if it fails.

How does VRRP work?

When the VRRP group is formed, one router is elected as the master router, and the others are designated as backup routers. The master router is responsible for forwarding packets sent to the virtual IP address, while the backup routers monitor the master router and take over if it fails. The routers in the group communicate with each other using VRRP messages, which are sent at regular intervals.

If the master router stops responding, the backup router with the highest priority takes over as the new master router. The new master router then starts forwarding packets sent to the virtual IP address. This ensures that there is always a master router ready to handle network traffic.

How to set up VRRP with MikroTik?

Setting up VRRP with MikroTik is relatively straightforward. Here are the steps:

Create a bridge interface and add your Ethernet interfaces to it.
Create a VRRP instance and assign it to the bridge interface.
Configure the VRRP instance with the desired virtual IP address and priority.
Configure the VRRP instance on the backup routers with a higher priority than the master router.
Configure the backup routers to track the master router and take over if it fails.

Benefits of using VRRP with MikroTik

Using VRRP with MikroTik has several benefits:

High availability: VRRP ensures that there is always a functional router available to handle network traffic.
Robustness: If one of the routers fails, the others in the group can take over without disruption to the network.
Easy to manage: VRRP is easy to set up and manage.
Traffic balancing: If there are multiple routers in the group, VRRP can be configured to distribute traffic among them.

Conclusion

Overall, VRRP is an essential networking technique that can enable high availability and robustness in your network infrastructure. By using VRRP with MikroTik, you can ensure that your network continues to function even if one of your routers fails. With its easy setup and management, VRRP is a powerful tool that should be in every network administrator's arsenal.
