    first i tried the setup with my cisco multi layer switch and with linux routers.

    if you need more information please let me know.

    it think it can be the same issue as the "vlanpcp" .

    thank you in advance</full-duplex></performnud,auto_linklocal></rxcsum,txcsum,tso4></up,broadcast,running,allmulti,simplex,multicast,staticarp>
