Hello,

On a network running RSTP, some devices use STP. When RSTP-enabled switches detect a topology change, which method is used by the RSTP-enabled switches to notify STP-enabled switches of the topology change?

Thanks.

Hello,

STP BPDUs with the TC is used. After enabling TC BPDU attack defense on a switch, you can set the number of times the device processes TC BPDUs within a given time. If this number is exceeded, the switch processes only the specified number of TC BPDUs. Excess TC BPDUs are processed in one go by the switch after the specified period expires. This function prevents the switch from frequently deleting its MAC address entries and ARP entries, reducing the load on the switch, and guaranteeing network stability.
