Roberto, Could you post your configuration and show output? I tried on on
a physical and a multipoint subnet interface (frame-relay), it doesn't
work. Whichever was that last key (youngest) created on the interface, is
the one ospf used in the hello packets to all its neighbors. I just
couldn't make it to use different key to different neighbors, am I missing
something? or mis-read the requirement.
A question for IPExpert workbootk users:
This showed up in IPExpert's workbook lab36, ospf section. And the solution
looks similar to the config posted below, only the hub was using a
"multipoint subinterface" the spokes are the physical frame interface. Was
it verified in a lab?
You help is highly appreciated.
