I think you are saying that r2 is a multipoint frame relay interface hub
router, with spokes r1 and r2 on the same subnet.
You don't state specifically, but let's assume you are talking about
OSPF interface authentication. If r2 is an OSPF point-to-multipoint or
NBMA interface and you configure authentication between r2 and r1 then
you must also configure it on r3. If not, the r3-r2 OSPF link will go
down. If r2 has separate OSPF point-to-point interfaces to r1 and r3
then you could get away with configuring only the one link for
authentication.

Is it possible to authenticate only r1 and r2. and no authentication
between r2 and r3.
here r2 and only one interface, and it is connected over frame relay to
r1
and r3.
Thanks,
