Question 371 · 504 in bank
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?
Show answer
Answer: B
Explanation
The correct is B. A = Define vPC role and the lowest value is the Master B = Peer-Switch feature allows the vPC peers use the same STP root ID as well as the same bridge ID. C = System MAC address of vPC domain, which is used for operations that are confined to the link-scope, such as LACP. D = The vPC peer-gateway capability allows a vPC switch to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer.
