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?
Answer
Adding the dual-stack all-interfaces router subcommand for EIGRPv6
Adding the dual-stack interface subcommand to interfaces G0/0 and S0/0/0
Adding the ipv6 eigrp asn interface subcommand to interfaces G0/0 and S0/0/0
Adding the dual-stack all-interfaces router subcommand for EIGRPv4
Question 2
Question
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 ?
Answer
Interface bandwidth
Hello timer
Variance
Maximum paths
Question 3
Question
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?
Answer
The EIGRPv6 configuration uses the router eigrp asn global command
Both protocols use the router-id router-id router subcommand
Both protocols use the network network-number router subcommand
The EIGRPv6 configuration uses the ipv6 eigrp asn interface subcommand
Question 4
Question
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?
Answer
Make R9’s G0/0 interface passive.
Change R2’s EIGRP ASN to some other number, but otherwise keep the same configuration.
Change the Hello timers on all of R1’s interfaces from 5 to 4.
Change R1’s EIGRP ASN to some other number, but otherwise keep the same configuration
Question 5
Question
R1 and R2 are routers that connect to the same VLAN. Which of the answers lists an item that can prevent the two routers from becoming EIGRPv6 neighbors? (Choose two answers .)
Answer
Mismatched Hello timers
Mismatched ASNs
IPv6 addresses in different subnets
Using the same router ID
One passive router interface (used on this link)
Question 6
Question
The output of the show ipv6 eigrp neighbors command from R2 lists one neighbor. Which of the following answers is correct about the meaning of the output of the command in this example?
