interesting way to put the question. but...... 172.16.0.0/12 and 192.168.0.0/16 are CIDR notation. any subnets within those ranges would default to the classfull values based upon the first couple of bits. remembering that 0 in the first position is class A, 10 in the first two positions indicate class B, and 110 in the first three positions indicate class C. RIP and IGRP are classful, and would note the classful values.
and my apologies for putting this answer into the BGP thread. The news server ate my post, and......
