Uh-oh. We're about to acquire quite a number of PM-2ER-30 and PM-2E-30.
Initially, we have 4 dial-up points and 2 of the dial-up points have 30
phone lines and the other 2 have 50 lines. We got 3 class C addresses
and i subnet the two. I subnet them with 4 bits and 3 bits but the other
one, i didn't subnet it.
Since PM only supports subnetting of 4 bits, i guess i have to adjust my
subnets. Or do you have other suggestions?
BTW, i heard of a new ruling in subnetting: you're now allowed to used
the lowest value of the subnet. Is this true or is this only
applicable to Cisco Products?
Thanks.
