I am not able to find solution for this!!

[00u1dfxe6upJF5Qai5d7]

A global IT company is mainly based in the EU. Recently, the company
had decided to move to the Australian market. DAF has decided to establish three
main branches in three of the major Australian cities (Sydney, Melbourne and
Perth).
The Sydney branch will have up to 600 employees.
The Melbourne branch will have up to 400 employees.
Perth branch will have up to 200 employees.Each branch has its own Application, Database and DNS server. It is understood
that employees will be able to communicate and access data from different servers
within the three sites.
You have been hired and have been asked to analyze, design and configure the new
network.
Use Network Address: 172.xx.0.0/16 and create the desired subnets.

What will be the solution of below questions:

1) Allocated Subnet Address and Subnet Mask
2) Network Address
3) Default Gateway Address
4) Valid Host Address Range
5) Broadcast Address

for:

a) Sydney, b) Melbourne, c) Perth, d) Network Between Sydney and Melbourne, e) Network Between Sydney and Perth, f) Network Between Melbourne and Perth

Will i get help??

[Joseph W. Doherty]

"Will i get help??"

Possibly.  What are your expectations?

You also realize, looking for posted responses, within 20 minutes, on a Sunday, from volunteers, might be a bit of an over expectation?

Further, your posting doesn't clarify exactly what you need help on, unless your looking for a complete solution to what appears to be a homework assignment?

Paul's posting has provided a possible solution, but if this is a homework assignment, do you have an understanding of what/why Paul is suggesting what he has posted?  If this is a homework assignment, or even a real network, are you aware of issues about subnet sizes?  Might you want the "servers" on a different network from "users", etc.?

Are you also familiar with Cisco's learning network?  Where have you "looked" for a solution that you could not find?

BTW, in my response, I'm not trying to be harsh, but if this is something like a homework assignment, I would like to see you actually "learn".

@Joseph W. Doherty, the OP has to submit the answers to the homework/assignment so he can go back to his game console.  

(DAF has been operating in `straya for yonks.)

Sorry!! Actually i was expecting the Design, using cisco packet tracer!! Subnetting of network was already completed by me!!

[Joseph W. Doherty]

Ok, and what part of the design is a problem for you?

[00u1dfxe6upJF5Qai5d7]

The network between sites!! i connected hosts to switches and switches to router for each site.. Problem is how should i connect three sites..?

[Joseph W. Doherty]

Connect each site router to each of the other two site routers using some form of a point-to-point (WAN) link.  This will create a full mesh network, looking like a triangle.  (I suspect that's what Paul had in mind for the purpose of the D, E and F networks.)

Sorry for late reply! Actually i was also expecting design [using CPT]. This subnetting was already completed
