Scenario #2 – (With STP, No Pseudo VLAN)
When STP is enabled, extra redundant network paths between APs will be
disabled, hence preventing multiple active network paths in-between any two
APs.
If one of the APs is down, the STP algorithm will reactivate one of the redundant
paths so that the network connection will not be lost.
All wireless users will be able to communicate with each other if they are
associated to the APs that are in the same WDS zone.
