Hi Pranab,
I guess you missed to provide proper L3/L2 mapping on frame-relay links,
and this is not a OSPF issue in reality.
At spokes you need at least one L3/L2 mapping for HUB, and if you want
reachability between spokes, you also need extra mappings for spoke to
spoke traffic. For spoke-to-spoke mapping you don't need broadcast, I
hope this help you.
Regards,
Kemal

Subject: Policy based routing in partially-meshed FR/OSPF network
I have the following hub and spoke FR network:
R2
(multi-point)
/ \
dlci 102/201 / \ dlci 302/203
/ \
R1 R3
With ospf network type configured as non-broadcast and manually
configuring
R2 as DR and R1/R3 as neighbors, I am able to bring the OSPF adjacencies
up.
I'm using a /24 subnet so R3 shows up as directly connected to R1. Now
when
I try to ping R3 from R1, it fails because there is no direct
connectivity
between R1 and R3. Other than policy-based routing (making R2 as
next-hop),
is there an another way of make R1 and R3 reachable to each other?
Appreciate your help.
Pranab
