Brian,
It's the other way around. You can use the summary-address command to
summarize routes coming in from external protocols. For this reason doing
redistribute connected on a /26 into ospf and then summarizing to /24 will
solve most of these situations. I just hope they'll accept this strategy in
the lab...
