bpdu's

On a switched network with spanning tree, does each switch send bpdu's to its directly connected switches ? snd so dont flood them to all switches ?

Each BDPU is sent with a L2 multicast destination address, so it will get flooded out all of its ports.

Hi Carl,

Once the spanning tree has converged, the configuration BPDU's are generated by the root switch and are relayed by other switches.

The TCN BPDU's are generated from the switches and they move towards the root.
