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 22.214.171.124/24 subnet. The backbone also supports two further routers SALES and RESEARCH. There is one Sales subnetwork 126.96.36.199/23, and two research subnetworks 188.8.131.52/24 and 184.108.40.206/26.
If the Interface addresses are: • i1–220.127.116.11 • i2–18.104.22.168 • i3–22.214.171.124 • i4–126.96.36.199 • i5–188.8.131.52 • i6–184.108.40.206
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.
