I'm having difficulties understanding the solution to the following question:
Consider the following description of a LAN:
The main Internet connection is connected to our gateway router. This in turn is part of the backbone network on the 184.108.40.206/24 subnet. The backbone also supports two further routers SALES and RESEARCH. There is one Sales subnetwork 220.127.116.11/23, and two research subnetworks 18.104.22.168/24 and 22.214.171.124/26.
If the Interface addresses are: • i1–126.96.36.199 • i2–188.8.131.52 • i3–184.108.40.206 • i4–220.127.116.11 • i5–18.104.22.168 • i6–22.214.171.124
What are the routing tables for the SALES and RESEARCH routers?
How is the via and interface column derived in the solution?
Thanks in advance.
