Techniques are provided herein to support roaming of wireless mobile client devices from one wireless local area network access point device to another wireless local area network access point device. Neighbor discovery messages are received from wireless mobile client devices. A neighbor discovery message specifies a target address for a neighbor discovery function. A response to a neighbor discovery message is sent to a wireless mobile client device such that the response message appears to have been sent by a wireless mobile client device that has an address that corresponds to the target address of the neighbor discovery message.
