Topology Example Four
Consider a building with three floors looking to deploy a switch on each floor. The APs on
each floor would be connected via a L2/L3 network to local switch on that floor and would
bootstrap with the same switch.
Each of these Local switches is on a different VLAN and subnet. The clients associating with
each of these would also belong to the same VLAN and subnet. The switches can act as the
DHCP server for the subnet or can use an external DHCP server.
To enable seamless mobility between the subnets as the clients move, mobility needs to be
enabled
A brief description of the requirements that this topology satisfies is discussed below.
z
Redundancy
This topology consists of N local switches and 1 master switch. The master
switch serves as a backup for each of the local switches.
