You should have the hub r5 as the DR, set priority on spoke interfaces
to 0 and reboot all routers. Non-broadcast uses unicast so the
broadcast parameter is moot but always a good practice. The neighbor
command should be used only on routers capable of becoming DR or BDR.
In this case, only on r5, and it must be there. This is a basic issue
in frame-relay hub to spoke configurations.
