   Here is my configs for OSPF. Refer to Caslow book for checking the
   status. It should say DNA (do not age) when you type show ip ospf
   neigh.
   because hello packets are constantly keeping the line. Restrict your
   access-list with pings only for example. What it means is that OSPF
   routes are still even if the link is down.

     That's the command. Are you doing it on both ends? Are you sure
     it's OSPF hellos that are bringing up the line; what about
