Sending Bridge ID sent from a MST region

[Huan NG]

Hi all,

In the interoperation environment between an MST region and a PVST region. Let's say a root bridge (CIST bridge) is elected in the PVST region. In this case, when an MST boundary switch (Ex: SW1) sends BPDUs to another switch in PVST, what bridge ID will this switch advertise? Is it the BID of SW1 or the BID of the IST Master elected within the MST region?
Could someone shed some light on this? Thank you!

Are you still facing this issue?

Not an issue that I'm facing.
But just a question to understand more about MST and PVST interoperability
