Ah.... the old "OSPF over frame relay" problem!
You, sir, have discovered one of the CCIE core topics - something you MUST
know inside out to pass your Lab.
This isn't a "strange problem". This is a well known behaviors that gets to
the heart of OSPF and NMBA.
The fact that you are asking the question indicates you need to study OSPF a
little more. Got your Caslow handy? Got the RFC? Doyle? Slattery?
My own advice - change your focus from one of memorizing configurations that
get things to work to one of intimately understanding the behaviours and the
issues.
Best wishes in your studies.

Hi Guys..
Facing some strange problem in OSPF..
DO u know any condition if two routers become adjacent but still cant
exchange routes???What could be the reasons for it?
In this Lab, We have 2 subinterfaces on R1.One multipoint subinterface is
connected to two routers R2 & R3 physical interfaces.
The other PtP subinterface on R1 is connected to R4 physical interface.
Now problem is that we are not allowed to use IP OSPF NETWORK COMMADN
on these interfaces in order to make the same network type.
The problem I m facing is on R1 & R4 link.When I applied debug ip ospf,I
see Hello mismatch SO I match the Hello values on both sides .AFter that I
am able to see that R4 is now adjacent with R1 Point to point interface but
Still I cant see any route from R1 coming on R4 or vice versa..
Any Suggestion GUYSSSS....;
Thanks a lot!!!!
