Re: Brainstorming: Subneting and VLSM

It's important to have a strong understanding of everything on the
blueprint. In my opinion you should be fairly comfortable with the basics
of regular expressions and know how to compose IPv6 ACLs. VLSM and
subnetting on the other hand is just so fundamental to everything we do, in
my opinion any great engineer or CCIE candidate needs to be able to do it
on the fly, in your head thoroughly and accurately

When I personally interview for technical positions, my first 2 or 3 are
always subnetting related...and I expect the candidate at a minimum to be
able to do it by hand with a pen and paper. Anything less is not what I
consider to be up to par.
