[zebra 22928] Multipath

Hi,
I have tested static and RIP and it was ok. Now I am trying to test 
OSPF. I am able to get OSPF neighbor from one to one if it is like 
bellow i am not getting all neighbors:

R1
|
|>>>>>>Back to back cross UTP cable
|
R2 (R2 is not getting any neighbor)
|
|>>>>>>Through Hub
|
R3

If i connect R1 directly to R3 its ok but if i go through R2 its not 
working. So i thought its about multipath I recompiled the quagga with 
--enable-multipath=0 and my kernel (2.4) status is as bellow but still 
the result is same.

make menuconfig result
