Tim - What do you think about just entering the shutdown command on the
interface that the current DR is located? This of course will depend upon
your network and may not be an appropriate idea. Once the DR is down, the
BDR will be promoted and a new election will take place for the new BDR
slot. (This of course assumes that you want the current BDR elected to DR.)
Once the new election has taken place, you can issue the no shutdown command
on the old DR.
