No. > What is the difference between a BPDU and a Configuration BPDU? Configuration BPDU is just one type of BPDU. There are two types: 1. Configuration BPDU 2.

Non-root bridges send their own configuration BPDU, which contains information about root bridge. But, they also contain information about cost to root bridge, bridge id and port id that sent BPDU, etc., so each BPDU on the network is different.
