Suggested Answer: C 🗳️
RIPv1, RIPv2, IGRP, and EIGRP all auto-summarize classful boundaries by default (OSPF does not). To make discontinuous networks work, meaning you don't want classful boundries to summarize, you need to turn off auto-summary. http://www.ciscopress.com/articles/article.asp?p=174107&seqNum=3
