association
1) A station is associated with AP 1, which is connected to AC 1.
2) The station disassociates with AP 1 and roams to AP 3 connected to AC 2. Now AC 2 is the FA for
the station.
3) The station is associated with AP 3 through inter-AC roam association. Prior to inter-AC roaming,
AC 1 should synchronize the station information with AC 2 through an IACTP tunnel.
4) The station then disassociates with AP 3 and roams back to AP 2 connected to AC 1, which is its
HA.
