L3-Mobility on IAPs

    Hi,

     

    I'm trying to implement L3-mobility between two Instant networks.
    My test network is formed by a layer-3 switch to which are connected, on two different VLANs (VLAN1 and VLAN2), two IAP-105.

    VLAN1 192.168.1.100/24
    IAP1 192.168.1.111
    VC1 192.168.1.110

    VLAN2 192.168.2.100/24
    IAP2 192.168.2.111
    VC2 192.168.2.110

    I have so two Virtual Controllers with the same SSID "Test-Mobility", configured in the same way:

       Client IP assignment: Virtual controller assignment
       Security: Personal
            Key management: WPA2-PSK
            Passphrase: mobility
            MAC Authentication: Disabled
            Access: Network Based: Assign VLAN1 (2)

    With my laptop, I initially join the IAP2 and I obtain the IP address 192.168.2.204; I start a session ping to the VC1 and VC2, wich respond correctly.
    Then I move from the area covered by IAP2 to the one covered by IAP1, always with the active ping sessions: here is the problem! My laptop starts to lose ping packets to both VCs, but my laptop doesn't say me that the WiFi connection is lost!
    After a  long while, I come back to IAP2 area, and ping continue to be lost!

    To have success pings, i have to disconnect and reconnect to the SSID.
    I therefore conclude that the roaming doesn't happen!

    PS: To configure the L3-mobility I followed Chapter 8 of the pdf "Instant Access Point User Guide 6.1.3.4-3.1.0.0"

    Does anyone have any idea or suggestion?

    Thanks,
