In traditional link aggregation, all links in a bundle must terminate on a single switch, which creates a potential single point of failure. MLAG addresses this limitation by enabling the links to terminate on different physical switches, ensuring high availability and fault tolerance.

1. Redundancy: If one switch in the MLAG pair fails, the aggregated links continue to operate through the other switch.

2. Load Balancing: Traffic is distributed across all active links in the MLAG group, optimizing bandwidth utilization.

3. Seamless Failover: MLAG ensures minimal disruption during a link or switch failure, making it ideal for mission-critical applications.

4. Scalability: Enables the expansion of network capacity by simply adding more switches to the MLAG configuration.

• MLAG is built on standard link aggregation protocols like LACP (Link Aggregation Control Protocol).

• Two or more switches form an MLAG domain by synchronizing state information over a dedicated interconnect, known as a peer link.

• Connected devices perceive the MLAG setup as a single switch, simplifying configurations and improving compatibility.

• Data Centers: For connecting servers with dual-homed connections to separate switches.

• Campus Networks: Providing resilient uplinks to core switches.

• High-Performance Networks: Supporting applications that demand high throughput and low latency.

MLAG empowers network administrators to achieve resilient, high-performance architectures while simplifying operational complexities.
