Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 424

An engineer configured an environment that contains the vPC and non-vPC switches. However, it was noticed that the downstream non-vPC switches do not receive the same STP bridge ID from the upstream vPC switch peers. Which vPC feature must be implemented to ensure that vPC and non-vPC switches receive the same STP bridge ID from the upstream vPC switch peers?

Answer options

Correct answer: B

Explanation

The correct answer is B, 'peer-switch', as it allows the vPC switches to share the STP bridge ID with the downstream non-vPC switches, ensuring consistent behavior across the network. The other options, such as A (vpc local role-priority), C (system-mac), and D (peer-gateway), do not address the need for synchronized STP bridge IDs between vPC and non-vPC switches.
