Hey!
LAB: OSPF over multipoint frame relay (hub and 2 spokers).
Neighbors are not coming up.
Wireshark capture is showing 1-1 hello packets to 192.168.0.66 and to 192.168.0.67 but that's all.
Neighbor command is not shown in the sh run, and the prioriti is 0.

The essence of your problem is that assigning ip ospf priority 0 on all of the serial interfaces is preventing any router from becoming DR. And on a multipoint connection some router needs to function as DR. My suggestion is to configure the priority to 1 on R1. I believe that this will solve your problem.
