BASIC NETWORK TOPOLOGY ADVICE

Hi Im trying to put together all the skills I have learn't and I appreciate that it is not perfect so please do not be too critical as all I wish to do is make use of the equipment I actually have and be able to put it down on paper and get it too work.

Once done I can then fine tune things next time round, knowing that I have a Foundation of knowledge knowing it actually works! As you will see Ive added the following for practical experience:

- NAT     - Separates Internal from External network
- CBAC   - Acts as a Firewall
- IP CEF - Cisco Express Forwarding - Load sharing less processor intensive instead of standard 'no ip route-cache' - for 'per-packet'
- FEC     - Provides extra throughput but can be upto 16 Gbps even upto 8 Copper cables are used
- VTP     - Server & Client
- Vlan    - Single vlan 1
- DHCP  - Allocates IP Addresses to Host client pc's
- DNS - Domain Name Service

Qns1. My Residential ISP - Netgear router runs Dhcp which I can disable which hopefully wont affect my diagram..? (Not ideal I know) Its all I have for Internet Access..!

Qns2. Can anyone advise?

Yes, disable DHCP on the netgear. Run dhcp on the Win 2k3 box.
You don't need VTP. You only have one vlan/
You don't need Rip. Just add a static route. Honestly, what is the purpose of having the 2500 in the topology. I can understand the 2600 because you want to use CBAC, but no need for the 2500. You really don't even need the netgear, just use the 2600 router.

Why the bridge between the two computers.

Hi again Soulja,

Dhcp - Ok good.
VTP   - Ok I will do 'Router-on-stick' so can use 2 Vlans - Forgot about that..!!
RIP    - I know I do not have upto 15 routers so why not I use 'Static routes' or something but for the purposes of 'Practical knowledge', I decided to use the RIP and for practice I will add 'Static routes' & Floating.....
Netgear Router - As it does not configure 'Routing Protocols' that is why Ive just added a 2500 although yes I have another 2600/3600 anyway so that I can use Routing protocols for practical experience.

Why the bridge between the two computers - Because Ive never done it before and isnt it or can it be used for 'Backup' or something ?
In Advanced Properties I will 'Move' Master DC to TOP and Secondary DC to bottom of Binding..

When you say I dont need the 'Netgear' this is my Internet connection that my ISP has provided so it 'HAS' to be used..

Okay.  I didn't know the router was ISP provided. That being said, and in response to your comments, then you are fine.

Ok good...!! One more thing I wish to also configure 'HSRP' so if I remove the 2500 for another 2600 is this ok?

Can 'HSRP' function on Serial interfaces aswell ?

Once Ive done this practicallly would you say using CBAC and Kaspersky is enough to protect?
What if I run 'SCW' as another layer of added security for the Windows 2003 is this ok or the norm?
What about 'Bridging' the 2 DC's as Ive suggested - Does this provide a Backup if configured exactly the same?

Don JohnstonInstructorCommented:
You can't do HSRP in your topology. That requires the routers to have interfaces on the same network as the clients.

Ok I will look at that on another scenario..What about the other stuff Ive mentioned..is it the norm..?

If you want to do more with your routers and switches I would suggest putting in a "simple" basic network and then adding to the "inside" of it rather than than creating a complex "live" network, as once you have the "live" network running, you will be limited in what you can do to it to keep it running.

Hi ArneLovius,  This is only a Residential ISP connection just for test purposes and just filling in the gaps around my Foundation Basic Network diagram on 'main' thread for practical memory understanding more from a corporate point of view rather than small-to-medium businesses!!!thats all then yes of course I will simplify it later.....

Later I will do another Network Diagram around:

Routing:
- Redistribution
- passive-interfaces
- Distribute-lists
Switches:
Root bridge
Designated bridge
Priorities
Cost etc

When you say building a complex network I will be limited in what I can do to keep it running how so ?

Im aware this network is NOT ideal..!!As just trying to involve everything I've learned over a period and put together and so what better way than to use my own thoughts like now and do what Im doing now!!!

ArneLoviusCommented:
In which case, just do it, and then see how you can add to it and optimise it

if you want to "build" complex network setups, I would suggest taking a look at GNS3...

mikey250Author Commented:
Hi ArneLovius, yes I have downloaded 'GNS3' but not got round to installing it yet, not sure if it is literally straight-forward to do but yes I will evolve over to using 'GNS3', just wanted to get my physical practical knowledge upto to a point as there are those out there who can do the virtual stuff but cannot do practical and in this day and age it is nice to do both...

Qns1. It would be nice if you could explain a little about what you said:

When you say building a complex network I will be limited in what I can do to keep it running how so ?

Thanks for the advice!!!!!!!!!!!!!!

ArneLoviusCommented:
I'd suggest spending the time to get GNS3 up and running would be a very worthwhile investment for you.

it will enable  you to "test" out multiple scenarios while not affecting your "live" network.

Hi ArneLovius, I have a laptop that has wireless so Im ok as my hardware and software is used specifically for my practical experience enhancements so I dont mind, but definately eventually I will move to GNS3 and can take a break from all this mess and cable and pc's/servers everywhere and just sit on a laptop and do virtual..

I do wish to teach myself:

Cisco PIX 501 Firwalls
ASA
4948
3560
7200
6500

Not sure if this is all on GNS3 yet..!!

mikey250Author Commented:
The reason for me spending a lot of serous time doing this is because since this economic crisis around the world I cannot get back to employment.....!!

So you advice is appreciated!!

ArneLoviusCommented:
you can learn more using GNS3 than the physical equipment that you have.

but, you need to spend time reading and understanding the concepts before trying to implement.

http://www.gns3-labs.com/ might be a good place to start

Hi ArneLovius, Yes I know I will evolve over to GNS3 eventually.....!! Appreciated!!
