Refer to the exhibit. A network administrator wants to load-balance the traffic that is coming from the LAN that is attached to router R1 and going to the 10.10.10.0/24 network. The output from the routing table on R1 reveals that the traffic is flowing through router R3 only. What is the reason for this traffic behavior?
RIP redistribution into the EIGRP routing process is not performed on R4.
EIGRP does not load-balance automatically over equal-cost paths.
A variance command is missing under the EIGRP configuration on R3 and R4.
The seed metrics should be configured with the default metrics command under the EIGRP process on R3.
The passive-interface default command on R4 is blocking the RIP updates that are being propagated into the EIGRP routing domain.
