The only way to get rid of the DNA statement in the LSA's and get the route
inserted into the routing table on router 1 was to make the subinterface on
R4 1.1 a NBMA OSPF Network. It would not work with the subint as a PTP.
I'm trying to find out the reason on cisco.com and doc CD, no joy yet...But
it is working now. ..OSPF is a killer but you gotta love it !!!!!...Thanks
for the reponsesl.......Bob
