OSPF has a TTL of 1 in its packets. And if your hub is down, aren't you
screwed anyway?
In a nutshell, no, don't elect a BDR on hub/spoke networks unless the BDR is
a second hub that has full reachability of everyone.

Subject: OSPF BDR on a spoke
Hi Group,
If I enable a neighbor statement(s) on a spoke router, is it
possible to configure it as a BDR, without having full mesh or at least a
partial mesh?
R2(s0)______________(s0)R4
|\
| \ (FR network)
| \___________(s0)R6
|
| (Point2Multi)
|______________(s1)R5
Here is the situation, (OSPF config)
No sub interfaces allowed, Single subnet, Only Frame maps allowed are on R2.
R2 is configured as the DR. Is it possible to set one of the spoke routers
as a BDR when there is not direct connectivity to the BDR from the rest of
the spokes?
Thanks,
Raj
