Which of the following statements is false about M-LAG deployment?

M-LAG (Multi-Chassis Link Aggregation) on Huawei CE series switches enhances high availability and load balancing by making two switches appear as one. Let’s evaluate each statement:

A. Multi-level M-LAG is mainly used to construct a large Layer 2 network in a DCN or directly connect DCNs at Layer 2:This is true. Multi-level M-LAG extends the topology across multiple layers or data centers, facilitating large Layer 2 domains, a common use case in Huawei DCNs.TRUE.

B. In multi-level M-LAG networking, you can manually configure the root bridge to prevent STP loops:This is true. Manual configuration of the root bridge (e.g., using STP priority) is supported to optimize path selection and prevent loops, especially in complex M-LAG setups.TRUE.

C. Multi-level M-LAG must be configured based on V-STP:This is false. While V-STP can be used to prevent loops, M-LAG does not require V-STP specifically. Standard STP, RSTP, or MSTP can also be configured, depending on the network design. The requirement is loop prevention, not a mandatory V-STP dependency.FALSE.

D. M-LAG networking can be classified into single-level M-LAG networking and multi-level M-LAG networking:This is true. Single-level M-LAG connects two switches directly to devices, while multi-level M-LAG extends across additional layers or devices, a recognized classification in Huawei documentation.TRUE.

Thus,Cis the false statement because multi-level M-LAG does not mandate V-STP configuration.References:Huawei CloudEngine Series Switch Configuration Guide – M-LAG; HCIP-Data Center Network Training – M-LAG Deployment.
