Question

Shown below is the content of a routing table. Use the 3-step matching rules to find the nexthop router for arriving packets with the following destination IP addresses. For each forwarding decision, explain your reasoning.

Arriving Packet 1: 64.28.197.250

Arriving packet 2: 140.186.35.138

Arriving Packet 3: 196.230.90.31

Arriving Packet 4: 120.75.63.26

Note: 1. the outgoing router interface column is omitted from the table

2. Row 15 shows the default route

the answers I got are:

Arriving Packet 1: Next hop router should be row 8 Router B
Arriving Packet 2: Next hop router should be row 2 Router D
Arriving Packet 3: Next hop router should be row 11 Router C
Arriving Packet 4: Next hop router should be row 1 Router B

are these correct?
