Thanks Brian, Victor!
As you have pointed out, the sh ip ospf database <>
shows that the network is not reachable.. I thought that the hello parameter
change shud suffice and I can make the nonbroadcast and point to point network
work.... But its not like that.. The link was indeed very good and
informative..
Thank you for your assistance!
