Answer: A - The first parameter to be configured as a part of the IGRP routing process is the Autonomous System number.

Key Takeaway: Unlike RIP, IGRP has an additional parameter with the IGRP command, the autonomous system (AS) number. In general, the AS number refers to a number assigned to a single company or organization when it registers its connection to the Internet. IGRP does not need a registered AS number. For IGRP to work, all the routers should use the same AS number.
