Having a reliable, high-speed Internet connection is crucial. To achieve this, it is sometimes necessary to combine multiple links or interfaces into a single connection, and this is where Bonding in MikroTik RouterOS comes into play.

At the end of the article you will find a small test that will allow you assess the knowledge acquired in this reading

In this article, we will explore in detail what Bonding is, how it works, and how it can be implemented to improve the connection on your network.

 

What is Bonding in MikroTik RouterOS?

 

Bonding, also known as Link Aggregation or Trunking, is a technique that combines several network links or interfaces into a single, higher capacity channel. This technique is used to increase bandwidth, improve redundancy, and ensure a more stable connection.

 

In the context of MikroTik RouterOS, Bonding allows physical or virtual interfaces to be grouped into a single logical link, which facilitates management and improves performance. This is especially useful in situations where a single connection is not enough to meet network needs.

 

How does Bonding Work?

 

Bonding works by distributing incoming and outgoing network traffic between grouped interfaces. Depending on the configuration, traffic can be distributed using various algorithms, such as Balance-rr, Active-backup, broadcast, XOR, or 802.3ad (LACP). Here's how each of these methods works:

Balance-rr

Distributes traffic evenly between Ethernet interfaces.

Active backup

It uses one active Ethernet interface and one standby Ethernet interface. If the active interface fails, the standby interface is automatically activated.

Broadcast

Combines all Ethernet interfaces into a single virtual interface.

XOR

This algorithm uses an XOR function of MAC addresses to distribute traffic. Ensures that packets destined for a specific MAC address are always sent over the same interface in the group.

802.3ad (LACP)

Link Aggregation Control Protocol (LACP) is a standard that allows network devices to automatically negotiate and configure bonding. LACP ensures balanced distribution of traffic and provides redundancy.

Implementing Bonding in MikroTik RouterOS

 

Below are the basic steps to implement Bonding in MikroTik RouterOS:

 

1. Interface Selection

Decide which physical or virtual interfaces you want to group. These interfaces must be connected to the same network or network segment.

2. Create a Bonding Interface

In the MikroTik interfaces menu, create a new Bonding interface and give it a name.

3. Add Interfaces

Go to the “Interfaces” tab of the newly created Bonding interface and add the interfaces you have previously selected. Make sure they are all set correctly.

4. Bonding Mode Settings

Select the Bonding mode you want to use (for example, 802.3ad, XOR, Round Robin) and configure other parameters according to your needs.

5. IP Address Configuration

Assign an IP address to the Bonding interface so that it is accessible on your network.

6. Firewall Rules Configuration

If necessary, configure firewall rules to allow traffic through the Bonding interface.

7. Testing and Monitoring

Perform connectivity tests and monitor the performance of the Bonded connection to ensure it is working as intended.

 

Advantages of Bonding in MikroTik RouterOS

The implementation of Bonding in MikroTik RouterOS offers several significant advantages:

 

1. Greater Bandwidth

Bonding allows multiple links to be combined, resulting in greater bandwidth available for the network.

2. Redundancy

If one of the interfaces fails, traffic is automatically rerouted through the remaining interfaces, ensuring higher availability.

3. Load Balancing

Traffic is distributed equally between interfaces, avoiding congestion on a specific link.

4. Greater Fault Tolerance

The redundancy inherent in Bonding increases the fault tolerance of the network.

 

Common Usage Scenarios

Bonding is used in a variety of scenarios, including:

1. Internet connection:

For businesses that require a high-speed, highly available Internet connection, Bonding combines multiple service provider connections.

2. Business Networks:

Enterprise networks often use Bonding to balance load and ensure a stable connection.

3. Data Centers:

In data center environments, Bonding is used to improve the performance and redundancy of network connections.

4. Streaming Media:

In streaming media applications, such as online broadcasting, Bonding ensures a strong, uninterrupted connection.

 

In summary, Bonding in MikroTik RouterOS is a powerful technique to improve network connectivity, increase bandwidth, and ensure availability. With the right configuration and choosing the right interfaces, you can achieve a faster, more resilient network connection to meet the needs of your organization.
