Question 20 Discussion

Refer to the exhibits. An administrator has deployed two FortiSwitch devices, Core-1 and Core-2, as multichassis link aggregation group (MCLAG) peers. These switches are connected to FortiGate for FortiLink and to an access switch (Access-1) using an inter-switch link (ISL). After configuration, the administrator notices that both Core-1 and Core-2 are claiming to be the root bridge in the Multiple Spanning Tree Protocol (MSTP) topology. What explains this behavior? (Choose one answer)

  • A. FortiGate participates in MSTP and causes both switches to assume the root bridge role.
  • B. The ISL was not configured correctly, leading to MSTP inconsistency.
  • C. Both switches share the same bridge ID because MCLAG treats them as one logical switch.
  • D. MCLAG automatically disables STP on all peer switches.

Selected Answers: C


C is absolutelty correct.

The correct answer is C because the CLI outputs clearly show that both Core-1 and Core-2 share the exact same Bridge MAC address of 02090f000701. While standard switches each possess a unique Bridge ID, the MCLAG configuration synchronizes these parameters to allow the two physical devices to function as a single logical switch. This shared identity ensures that downstream devices view them as one unit for redundancy and loop prevention. Consequently, because this shared logical identity has the lowest Bridge ID in the network, both switches report that they are the root bridge.
