Hi Atanu,

thanks for helping.

I am not sure I understand you right. You say that on eth0 ospf packets 
from a router arrive that is in subnet 217.64.164.128? I am logging all 
traffic at the moment, and ospf packets on eth0 arrive only from 
217.64.170.233 which is the address of the upstream router (I checked on my 
first router).

And I do not understand
> area 217.64.164.128, which in your

In my configuration this is area 0.0.0.1 - do you think it SHOULD be area 
0.0.0.0? I thought that area 0.0.0.0 always is the area with the upstream 
connection.

Thanks again for your help.

Dirk
