Umit,
I'm almost sure that your interface is not a FasEthernet interface,
because I don't see why the suggested solutions would not work. This is
evident from your posted config. The solutions I suggested would work on
fastethernet interfaces only. Can you confirm this?
Per the Ip issue, your BVI does not need an IP address if you only want
to bridge IP traffic between the VLANs, but make sure the sub-interfaces
are in the same bridge group and that the vlan# in the "encapsulation isl
vlan#" corresponds to the VLANs that you already created on your switch.
