Refer to the exhibit.
The company uses EIGRP as the routing protocol. What path will packets take from a host
on the 192.168.10.192/26 network to a host on the LAN attached to router R1?
A.
The path of the packets will be R3 to R2 to R1.
B.
The path of the packets will be R3 to R1 to R2.
C.
The path of the packets will be both R3 to R2 to R1 AND R3 to R1.
D.
The path of the packets will be R3 to R1.
Explanation:
Host on the LAN attached to router R1 belongs to 192.168.10.64/26 subnet. From the output
of the routing table of R3 we learn this network can be reach via 192.168.10.9, which is an
IP address in 192.168.10.8/30 network (the network between R1 & R3) -> packets destined
for 192.168.10.64 will be routed from R3 -> R1 -> LAN on R1.
Just to share the codes:
Codes: C – connected, S – static, I – IGRP, R – RIP, M – mobile, B – BGP
D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area
N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2
E1 – OSPF external type 1, E2 – OSPF external type 2, E – EGP
i – IS-IS, L1 – IS-IS level-1, L2 – IS-IS level-2, * – candidate default
U – per-user static route, o – ODR
