5.2.3 Spanning Tree Protocol (STP)
The Spanning Tree Protocol (STP) helps to avoid bridged loops in a wireless network and ensures a loop-free topology for
bridged LAN (connected on both wireless and ethernet interface). Following is the step-by-step procedure explaining how STP
feature works:
a. Disable: In this state, STP is disabled and no traffic is allowed through wireless and ethernet interfaces of the bridged
LAN.
b. Listening: When STP is enabled, the AP devices exchange Bridge Protocol Data Unit (BPDU) packets in listening state.
These BPDU packets contain Bridge Priority and MAC address information, based on which a Root Bridge and
Designated Bridge are selected.
• Root Bridge: It is the device that has the lowest MAC address or highest priority. Based on a Root Bridge, the
shortest low cost path is selected and alternate high cost paths are blocked, therefore avoiding loops on the
network. Root Bridge transmits the network topology information continuously to other bridges on the
network.
• Designated Bridge: It is the device closest to the Root Bridge and is responsible for forwarding the data
towards the root port of the root bridge. Designated Bridge determines the shortest low cost path to the
destination, via root port. All the other devices in the network other than Root Bridge, act as Designated
Bridge.
c. Learning: Once the Root Bridge and Designated Bridge are selected, all the devices learn and update the Bridge
Priority and MAC address information in their learn table. Designated Bridge determines the shortest low cost path via
root port, to forward the packets to the destination.
