I've been wondering...
I have two iAP clusters in a large facility, we split the access points up (48 and 57 along a dividing wall in the building) into to two different "management" VLANs to have two clusters.
Clients are all dropped on the same L2 (VLAN20) and appear to roam without trouble.
Should I consider L3 roaming or is the fact that they're in the same L2 from different clusters still mean that they can roam "seamlessly"??
