A company is deploying a wireless network using lightweight APs. What is an advantage of Layer 2 roaming compared with Layer 3 roaming when wireless clients roam around the campus?

  • The process of Layer 2 roaming is faster.
  • A wireless client can keep the same IP address.
  • The roaming does not involve a WLC.
  • DHCP service is not required.

Explanation: Both Layer 2 and Layer 3 roams are intercontroller roaming. In intercontroller roaming, a client roams from one AP to another AP that is bound to a different WLC. If both APs are configured with the same VLAN and IP address subnet, the client has made a Layer 2 intercontroller roam and it stays on the same VLAN and subnet. The process of Layer 2 roaming is faster than Layer 3 roaming (usually less than 20 ms). Both Layer 2 roaming and Layer 3 roaming allow the client to keep the same IP address.
