A buddy and I are currently preparing for the BSCN exam.
One of the review questions involving route summarization is as follows:
172.21.136.0/24 and 172.21.143.0/24 can be summarized as: ??
We both came to the same conclusion:
^
172.21.136.0 -> 10101100.00
The block is 136-144 in the /21 range so you'd be right, though you'd also
be summarizing other addresses which you do not explicitly have connectivity
to.

Dyland,
you're right, it is a typo or something. As a sanity check (probably a BAD
habit) I use the subnet program offered by boson... according to that program:
172.21.134.0/21 = 172.21.128.1 to 172.21.235.254
while
172.21.136.0/21 = 172.21.128.1 to 172.21.136.1 to 172.21.143.254
so, I w
Derek... speaking of typo's my email was SUPPOSED to say:
172.21.134.0/21 = 172.21.128.1 to 172.21.135.254
while
172.21.136.0/21 = 172.21.136.1 to 172.21.143.254
