-
First, elect the root bridge. The election basis is bridge ID combined by
network bridge priority and network bridge MAC address. The network
bridge with the smallest bridge ID would be the root bridge in the network,
whose all ports are connected to the downstream bridge, so the roles of all
ports has became specified ports.
-
Next, the downstream network bridges that connect to the root bridge
would choose a
“strongest” brunch as the path to the root bridge
separately, so the roles of the corresponding port would be root port. Loop
this process to the edge of the network,
a tree would be generated when
the specified port and the root port are determined.
-
when the spanning tree is stabled (default value is 30 seconds) after a
while, the specified port and root port will enter forwarding state, and other
ports will enter block state.
-
STP BPDU would be sent from the specified ports of each network bridge
regularly to maintain the state of link. If the network topology has changed,
the spanning tree would be recalculated and the port state would be
changed as well.
