Hi everyone.
Happy new year!
I had an question about the TC bit advertised in a Root Bridge's STP BPDU.
I know that when the Root Bridge receives a TCN BPDU, it starts setting the TC bit in its config BPDUs to inform all the switches that there's been a topology change.
My question is: For how long does the Root Bridge keep setting the TC bit in its BPDUs?
Thanks,
Deepak
