Abstract:
A Wi-Fi controller identifies a mismatch between a first prefix of a first IPv6 address for a data packet corresponding to a first VLAN on which the data packet was sent from the station to the access point, and a prefix of a second IPv6 address for a second VLAN from which the data packet was transmitted from the access point to the Wi-Fi controller. Responsive to the VLAN mismatch identification, the Wi-Fi controller transmits an RA to the station with a preferred lifetime of 0, wherein subsequent communications use the second IPv6 address.
