as generally known on a broadcast multiacces-medium like ethernet multiple OSPF-Router perform an election of the designated and the backup designated router. If the designated router fails, the backup designated router succeed and a new backup designated router is elected. If the original designated router gets online again, no election will occour, because stability of the OSPF.
Now the question - how can I manually force the election of DR/BDR? Any ideas (beside reload of the designated router and shutdown of the interface pointing to the multiaccess-medium)?
You've mentioned the only options. This, as you eluded to, adds to OSPF's stability as well. As with ISIS the DIS is elected each time another with a higher priority is brought on to the Multi-Access medium. OSPF is very good in this way.
