An enterprise uses a dual-stack model of deployment for IPv4 and IPv6, using EIGRP as the routing protocol for both. Router R1 has IPv4 and IPv6 addresses on its G0/0 and S0/0/0 interfaces only, with EIGRPv4 and EIGRPv6 enabled on both interfaces. Which of the following answers is a valid way to configure R1 so that it enables EIGRPv6 on the exact same interfaces as EIGRPv4 in this case?

Which of the following configuration settings do not have a separate IPv4/EIGRPv4 and IPv6/EIGRPv6 setting, instead using one setting that both EIGRPv4 and EIGRPv6 both use ?

An enterprise uses a dual-stack model of deployment for IPv4 and IPv6, using EIGRP as the routing protocol for both. Router R1 has IPv4 and IPv6 addresses on its G0/0 and S0/0/0 interfaces only, with EIGRPv4 and EIGRPv6 enabled on both interfaces and the router ID explicitly set for both protocols. Comparing the EIGRPv4 and EIGRPv6 configuration, which of the following statements are true?

Three redundant IPv6 routes exist on R1 to reach IPv6 subnet 9 (2009:9:9:9::/64), a subnet connected to router R9’s G0/0 interface. R1’s current successor route uses R2 as the next hop, with feasible successor routes through routers R3 and R4. Then, another engineer makes changes to the configuration in the network, resulting in R1 having no routes to reach subnet 9. Which of the answers lists one configuration that would result in R1 having no routes at all to subnet 9?
