I thought of that solution (#3) but I wasn't sure if that was what he
was referring to. Usually, in the context of CCIE lab studies, the labs
state that you can't use static routes. However, this wasn't part of
the lab, it was just in the Hints section of a lab so that restriction
might not have applied. I'm sure you're right.
Also, a static route wouldn't suppress the more-specific subnets. Is
there a way similar to this to summarize routes AND to suppress the
more-specific subnets? Hmm.... food for thought.
I'm still at a loss about the fourth method. I wonder if it involves
some sort of incantation.
Thanks,
John

Here's my guess. I've included the first two for clarity.
1. Inter-area route summarization with commands of the form
"area 1 range 10.1.2.0 255.255.224.0"
2. External route summarization with commands of the form
"summary-address 10.1.2.0 225.255.224.0"
3. Static route of the form
"ip route 10.1.2.0 255.255.224.0 s0"
4. ??
