STP and RSTP Convergence

Hi

I'm studying for the ICND exam and have a basic question for some one. After STP/RSTP has converged what ports recieve BPDU. Is it all ports on all switches that are part of the active topology or just the trunk ports. If there is a hub connected to the topology do all hub ports recieve the BPDU?

I wish I had a diagram to make my question clearer.

I would appreciate any advice.

Re: STP and RSTP Convergence

All ports forward\recieve BPDUs. If you use a network monitor\capture program such as Etherreal you can view the BPDUs that are recieved on your port. BPDUs are sent\recieved on active and STP disabled ports, the disabled ports just don't act as a forwarding port for normal traffic. This is so that spanning-tree can keep an accurate loop free topology.

Hope that helps
