First of all, why would you want to have a DR and BDR election in your
hub & spoke frame-relay cloud?
I would suggest using a point-to-multipoint network type, which is the
right one for this.
For you assignment of building an OSPF adjacency without using a
virtual-link of tunnel I would suggest looking at 2 OSPF processes and
redistributing in each other. I don't know if it's possible to change
the TTL of OSPF, but seriously doubt it.
Sample config:
int fa0/0
ip add1.1.1.1 255.255.255.0
int fa0/1
ip add 2.2.2.2 255.255.255.0
router ospf 1
redist ospf 2 subnets
network 1.1.1.1 0.0.0.0 area 0
router ospf 2
redist ospf 1 subnets
network 2.2.2.2 0.0.0.0 area 0
Regards,
Rick
