High Availability And Redundancy In MikroTik Router Configuration Ensuring Uptime

In today's world of networking, a reliable and fail-safe routing protocol is essential. Mikrotik's VRRP protocol provides a solution to this issue. This article will explain the advantages and features of Mikrotik VRRP, particularly its interface tracking capabilities, which can improve the overall reliability of the protocol.

Improved Network Availability with VRRP

Mikrotik's Virtual Router Redundancy Protocol (VRRP) is widely used in both small and large networks. Its primary purpose is to improve network availability by allowing multiple routers to act as a single virtual router. This creates a backup in the event of a failure, taking over and ensuring that the network has continuous access.

With VRRP, a backup router takes over the active router's IP address when it goes down, ensuring continuous service. This protocol provides both load balancing and fault tolerance. To ensure this, the active router may broadcast group packets frequently to let other routers know of the current status.

Interface Tracking in VRRP

Mikrotik's VRRP protocol has a feature that is known as interface tracking. This feature allows the VRRP protocol to track the status of the interfaces of the various routers in the virtual router network. In case an interface fails, it communicates that information to other routers. If there are no routers' interfaces available to take over, the backup router will take over the primary router's interface.

The interface tracking feature has proven to be very useful in many scenarios. Suppose that there was only one interface in the virtual router network, and it failed. In that case, the backup router would have to cover the duties of the primary router, but under normal circumstances, it would never fail over because there is no reason for the backup router to take over the primary router's duties. However, because of the interface tracking feature, the backup router can take over in case of a failure, ensuring that the network is still up and running.

Configuration of Interface Tracking

The Mikrotik network administrators can configure interface tracking by following the steps given below:

Log into the Mikrotik router's terminal.
Enter the configuration command to start configuring the VRRP protocol: "/routing vrrp".
Next, select the user that you want to modify, or create a new user if one does not already exist.
Select the interface that you want to track.
Enter the VRRP ID applicable for the virtual router.
Enter the priority, which will determine which router will become the active router.

The example commands for this configuration step would be as follows:

/routing vrrp

add interface=ether1 vrid=1 version=3 priority=200

In the above example, the Mikrotik administrator is telling the VRRP protocol to track the state of the "ether1" interface and set the VRRP priority to 200. The protocol version has been set to three.

Advantages of Interface Tracking in VRRP

The interface tracking feature has several advantages that make it worth considering for your network. The benefits of interface tracking are as follows:

Improved Network Reliability

The interface tracking feature improves the reliability of the network by ensuring that the backup router takes over the primary router's duties in case of failure.

Cuts Overhead Costs

By using the interface tracking feature, the network administrators can avoid the need for expensive dedicated links to create redundant network paths. Interface tracking ensures that the backup routers are available to take over when needed.

Better Control of Network Failover

The interface tracking feature provides better control of network failover by allowing network administrators to configure which interfaces are important to the virtual router network.

Improved Network Management

The interface tracking feature improves overall network management, making it easier for network administrators to identify potential issues before they become bigger problems.
