- intracontroller roaming
- local-to-local roaming
- Layer 2 roaming
- Layer 3 roaming
Explanation: In a Cisco wireless network, when a client initiates an intercontroller roam, the two controllers involved can compare the VLAN numbers that are assigned to the respective WLAN interfaces. If the VLAN IDs are the same, the client undergoes a Layer 2 intercontroller roam (also called local-to-local roam) and can continue to use the original IP address on the new controller. If the two VLAN IDs differ, the controllers arrange a Layer 3 roam that will allow the client to keep using the same IP address.
