I'm trying to solve this schema, I been working on it a couple of hours, have I done it right? If I haven't can you please correct me?
Given the following schema, perform the corresponding subnets design, taking into consideration that you must take advantage of the maximum quantity of IP's available.
172.16.0.0 255.255.0.0 is a /16 network.
R1 network --> 40 hosts /26
R3 SW 4 network --> 70 hosts /25
R3 SW 5 network --> 80 hosts /25
R2 network for SW2 SW3 --> 150 hosts /24
Wireless R4 --> This one will use NAT probably, so it can be 192.168.1.0 /24 as default.
Networks between routers:
R1-R2 --> /26 (because there is a switch between them)
R3-R2 --> /30
R2-R4 --> /30
So there are 7 networks. IP schema:
R3 hosts SW4: 172.16.1.0 255.255.255.128 for 70 hosts
R3 hosts SW5: 172.16.1.128 255.255.255.128 for 80 hosts
R3 to R2: 172.16.2.0 255.255.255.252 for two interfaces
R2 hosts SW2/3: 172.16.0.0 255.255.255.0 for 150 hosts
Between R2 and R1: 172.16.2.0 255.255.255.192 for ~38 hosts
R2 to Wireless R4: 172.16.2.4 255.255.255.252 for two interfaces
