In this situation, R2 and R3 should never be eligible to be DR. If
R1 is down, the subnet effectively is down.
If you needed additional reliability (i.e., a BDR), add R4 with PVCs
to R1, R2, and R3. Be sure it can reach the same upstream router as
R1. If it's a backup, you may be able to get away with a less
powerful router.
