Yes, if you configure a multipoint subinterface...it defaults as a
non-broadcast. Then, just use the neighbor statements at the hub and
you should be good.

thanks for helping..
yes.. i'm not allow to use ip ospf network in all routers...
i double check my config.. and i notice there's a mistake..
R1 is actually a physical interface.. and its a non-broadcast..
hmm,i would think that the possible solution is to change the R1
interface
to point-multipoint.. which does not require DR/BDR and by using the
neighbot statement
it shold bring up the neighbor...
any comment ?

You'll want to make sure that your interface types agree.....you may be
able to form a relationship, but the routes will not pass. This has to
do with the DR/BDR.....take a look at the show ip ospf int command
.....are you not allowed to use the network command on all routers? Or,
just R1, or R2? If it is on a specific router....then you should change
the other router to agree. Or, you can change the interface to
agree.....point-to-point vs. point-to-multipoint.....(which don't use a
DR/BDR). The broadcast and non-broadcast need a DR/BDR. On your
example, you changed the one side to broadcast and everything worked. I
would assume that the other side is already set for broadcast. If you
have non-broadcast on both sides, you need to use the neighbor statement
at the DR(hub) to form the adjancency. Hope this helps.

in OSPF routing protocol over frame relay
R1 using Point to Multipoint
network 1.1.1.1 area 0
network 10.0.0.0 area 1
R2 using Point to point
network 1.1.1.2 area 0
network 20.0.0.0 area 2
and we're not allow to use ip ospf network command
i can form the neighbor adjacency by manually specified neighbor in
R1... and
change the hellointerval in R2..
when i do a sh ip ospf database... i can see network 20.0.0.0 in R1, and
network 10.0.0.0 in R2..
but it doesn't show up in routing table...
when i issue the command. ip ospf network broadcast in R2..
everything works fine...
any clue ?
