The path with the smallest cost will be used and extra redundant paths will be
disabled.
To explain the effect of STP & Pseudo VLAN on the wireless clients, we will
compare 3 separate scenarios.
Scenario #1
– (No STP, No Pseudo VLAN)
Referring to the illustration below, if the Spanning Tree Protocol (STP) and
Pseudo VLAN are not implemented in a network, all clients (Notebook#1, #2,
#3 & #4,) can access to one another, resulting in low level of data security. Due
to the redundant paths found in this network, broadcast packets will be
duplicated and forwarded endlessly resulting in a broadcast storm.
