Which of the following statements about the calculation process of MSTP is correct? (Multiple choice)

A. When calculating CST, external path costs are given priority, and internal path costs are compared only when external path costs are the same.

B. In MSTP, since the ports at both ends of the link may be designated ports in different instances, the ports at both ends of the link may both receive and send MST BPDUs at the same time.

C. The Alternate port and Backup port on the CST must be the region boundary port and must not be in the MST region.

D. The calculation process of MSTP is to first calculate CST and IST through MSTBPDU, and then the switches in the domain send MSTIBPDU to calculate the spanning tree of each instance.
