Ben,
What they mean is to add 8 subnet bits to the natural mask. In other
words, since 130.10.X.X is a class B address, which has a natural mask
of 255.255.0.0, they are indeed asking you to use a 24 bit mask.

Subject: VLSM and IP Addressing
I have a practice lab here that has the following addressing
requirement.
Configure all of the networks using network 130.10.X.X.
Use an 8-bit subnet mask unless otherwise specified.
This troubles me. Correct me if I'm wrong, but wouldn't this be a
problem for routing? I mean if you have the following senario:
|--R1------R2--|
R1's E0 is 130.1.1.1 255.0.0.0
R2's E0 is 130.2.2.2 255.0.0.0
Try getting any protocol to run on this network...it won't work will
it?
Essentially these two addresses are on the same network. Do you agree?
This
has me puzzled. This is the 2nd time I've seen this IP addressing
senario in
a practice lab today. I wouldn't know what to do if I was asked that
on the
lab.
OR...OR....does it mean to use a /24 mask eventhough it calls for an
8-bit subnet mask?
Thanks for the help,
Ben
