What is the value of the Type field in RSTP configuration BPDUs?
In RSTP configuration BPDUs, the value of the Type field is 0x02. This is because 0x00 is used for standard configuration BPDUs in STP, 0x80 is used for TCN BPDUs in STP, and 0x02 indicates RSTP or MST BPDUs.
RST BPDU are indentified by the BPDU type value 2(0x02).

I correct myself. I agree with jjbt_112 The right answer is c) 0x02 Indicates the BPDU type: 0x00: Configuration BPDU for STP 0x80: TCN BPDU for STP 0x02: RST BPDU or MST BPDU Explanation: https://support.huawei.com/enterprise/en/doc/EDOC1000178168/80efd6aa/mst-bpdus
