? What is the path a packet will take from the client to the server?
? Specify the router name and the outgoing interface at each hop.
? What kind of network does the client (10.0.0.1) belong to?

eth0 ethl Cost: 20 Cost:35 eth0 eth1 eth2 ethl eth0 eth2. Cost: 10 Client R1 Server 20.0.0.1 10.0.0.1 R1 R2 R3 Prefix Outgoing Interface Prefix Prefix Outgoing Interface Outgoing Interface 20.0.0.0/24 ho 20.0.0.0/24 eth0 20.0.0.0/24 eth1 20.0.0.0/27 eth1 20.0.0.0/27 eth1 20.0.0.0/27 eth1 10.0.0.0/26 ho 10.0.0.0/26 eth2 10.0.0.0/26 eth2

Explanation / Answer

1)
The path a packet will take from the client to the server is
client -> R1 -> R3 -> server [*It skips R2 because it costs extra 55]

2)
R1:
prefix outgoing interface
20.0.0.0/24 eth0
20.0..0./27 eth1
10.0.0.0/26       eth2

R2:
20.0.0.0/24 eth0
20.0..0./27 eth1
10.0.0.0/26       eth0

R3:
20.0.0.0/24 eth1
20.0..0./27 eth1
10.0.0.0/26       eth2

------------------------------------------------------------------------------
3)
Client belongs to R1-R3 network.
[*It skips R2 because it costs extra 55]
