Designing for Cisco Internetwork Solutions (DESGN, legacy) — Question 55

In a network with Enhanced Interior Gateway Routing Protocol (EIGRP) and IGRP using the same autonomous system number, what will happen on the router configured with both protocols?

Answer options

• A. Redistribution occurs automatically.
• B. Redistribution is not necessary.
• C. EIGRP assumes IGRP is a less capable protocol and overtakes it.
• D. Redistribution does not occur automatically.

Correct answer: A

Explanation

The correct answer is A because when both EIGRP and IGRP are configured in the same autonomous system, EIGRP automatically redistributes IGRP routes. Option B is incorrect as redistribution is indeed necessary for proper route exchange, while C and D misrepresent EIGRP's behavior regarding IGRP integration.
