doesn't oversummarize; 156.109.4.0/22 may not be thru the same router, also
156.109.36.0/22. Your solution results in fewer route table entries
advertised, but not optimal because of oversuummarization. Now if you know
that all the other possible networks that are in the summarization are or
will be thru this router (or never used at all), then this summary works and
is optimal. But you know what happens when you assume.
