Very interesting. Who is the DR for the way you have this configured? A point 2 multipoint link needs a DR. I have never gotten this to work and don't know of anyone who has.
I would very much like to see your configs and put it in my lab. Can you post the config?

yes , as i checked adjancy is formed , LSA also propagated , but it is not installed in the routing table ,
if you issue show ip ospf data router command in the hub router , you can see the LSA's from that spoke but it is listed as
.
Adv Router is not-reachable
> LS age: 1625
> Options: (No TOS-capability, DC)
> LS Type: Router Links
> Link State ID: 7.7.7.7
> Advertising Router: 7.7.7.7
> LS Seq Number: 80000005
> Checksum: 0xF048
> Length: 156
> Number of Links: 11
the same scenario i tried like this
in the hub i used ip ospf multi point interface and in the spoke i used ip opsf point to point network , then there is hello mis match , i adjusted spoke hello interval to match hub , then everything is fine ,adjancy is created , LSA advertised , and it is intsalled in the routing table too..
thanks guys

Not possible.
The problem is not just the timers. A sub interface will be a point-to-point
network type and there is No DR needed. If you can't do a subinterface on
the other side then it will be non-broadcast and will need a DR.
A Physical interface is Non-broadcast and needs a DR. And in frame the DR
should be on the hub. So changing the timers is not going to do anything. I
am quite sure this is not possible. If it is I would love to see how it is
done.
