passed ccna, studying for ccnp starting with bsci. frustrated by the variable formulas (still) for calculating max number subnets. With CCNA you assumed 2^subnetbits - 2; unless they specifically told you a classless protocol was in play.
But what I'm reading now to prepare for ccnp says just use 2^subnetbits no "minus two". I'm using ciscopress book also Bryant advantage.
So I'm practicing on learn to subnet just to build some speed in preparation for exam and, they still deploy the -2 part of the forumula.
Has Cisco yet specified exactly what their 'standard' is???
