BPDU stands for Bridge Protocol Data Unit, which is a data message transmitted between switches in a network to prevent loops and ensure loop-free spanning tree configurations.
BPDU Definition: BPDU stands for Bridge Protocol Data Unit, which is a data message transmitted between switches in a network to prevent loops and ensure loop-free spanning tree configurations.
BPDU, or Bridge Protocol Data Unit, is a message used in spanning tree protocol (STP) to detect and prevent network loops in Ethernet networks. BPDUs are exchanged between interconnected bridges and switches to establish a loop-free topology by electing a root bridge and designating a single path to reach it, thus preventing the creation of loops that could lead to network instability or outages.
BPDU is one of the topics you'll master in the CCNA Boot Camp.
