Cisco 3 Layer Network model


I Have been asked to provide a network costing for a cisco 3 layer network model.

I am after some help.

I need to know what would be some good choices re hardware for this model and their costs.
For the hardware listed below.

1. Router0
2. Router1
3. Switch2
4. Best choice of Internet for the solution
5. Is there any other special requirements for connecting these two sites between Router0 and Rotuer1.

I really I hope you can point me in the correct direction to what hardware would be a good choice for the parts that I need help.

Kindest Regards,

Hi Jason,

here i can suggest you some changes in topology. Is it bugged network or they want standard design. When we concentrate on standard we need to have more bugged.

For switch 2 , i will suggest don't use switch 2  at all. Are you going to subnet it or it will be flat network. If its flat network just put 2 48 port switch.

Yes fiber would be the best option but cost will be high as it is around 5 km. And i don't know whether it will support or not. For one customer i have used single mode fiber for around 2km. Its working fine. You just compare the service provider cost and fiber cost.
For fiber connectivity you need fiber cable,casing for fiber cable which will go underground.
and hardware side you need fiber module switch and fiber modules.

For Internet you can choose according to the requirement. Even you can go for broadband connection as they give very good speed.

To decide connectivity between two side.
1) compare cost with service provider      or    hardware,fiber,labor and other cost like taking permission.
2)If company is planning for short period then go for service provider. as i can see in other site you don't have much system. so there wont be much bandwidth requirement also. I think best option would be service provider from same service provider you take INTERNET also.
3)If they are OK with VPN suggest them VPN it will cheap and best for this scenario.

Hi Jason,

I can see to router0 around 80 hosts are connected. Keeping future expansion in mind you can go for 2811 or 2801, If budget is less you can go for 1841 also, If you think network will not grow more then 200 hosts.
In router1 i see around 10 hosts and i assume to Access point another 10 hosts will connect so for this you can go for 1841 router. For image you can choose advance sec or advance enterprice by which you can use your router as firewall aslo.. And in future if they plan for voice over ip(VOIP) they can use these routers with advance enterprice image.
Comming to you swithch you can go for 2960 with Poe if they planning VOIP phones in future or just normal 2960 switches. with number ports required. Usually you get 24 and 48 ports. Always choose more number of ports cos you dont know when network will grow, Always keep future in mind and decide. I hope i have answered your query please post if you have any questions.

Hi Praveen.

I would like to thank you so much for taking the time to reply to my question.

For switch3 and switch4 i have gone for the 2960.

I have decided to go for the 1841 router, for both Router0 and Router1.

For switch 6 I have decided to go for 8 port cisco cataylst 2940. small but will do the job.

I have one problem still I am not certain what I will use for Switch2??

Also what would be the best way to interconnect the two sites? Fibre? If so what other hardware would i need to do this?

What sort of internet connection would be required?

Thanks again,
