Half of your network uses RIPv2 and the other half runs OSPF. The networks do not communicate with each other. Which two of these factors describe the impact of activating EIGRP over each separate…

Question

Options

• AEIGRP will not be accepted when configured on the actual RIPv2 routers.
• BOSPF will no longer be used in the routing table, because you only have EIGRP internal routes
• COSPF will no longer be used in the routing table, because you only have EIGRP external routes
• DRIPv2 will populate its RIP database but not its routing table, because you only have EIGRP
• ERIPv2 will populate its RIP database but not its routing table, because you only have EIGRP
• FOSPF database will have RIPv2 routes.

Explanation

Administrative Distance (AD) determines which routing protocol's routes are installed in the routing table when multiple protocols know the same destination. EIGRP internal routes have AD 90, OSPF has AD 110, and RIPv2 has AD 120. When EIGRP is activated on OSPF routers: EIGRP internal routes (AD 90) beat OSPF routes (AD 110), so OSPF routes are displaced from the routing table - making B correct. OSPF still maintains its LSDB, but its routes won't appear in the IP routing table. When EIGRP is activated on RIPv2 routers: EIGRP internal routes (AD 90) beat RIP routes (AD 120), so RIP routes won't be installed in the routing table. However, RIP continues running and maintains its RIP database - making E correct. The routing table will show only EIGRP routes, but the RIP process itself keeps exchanging updates and building its internal database.
