    This is getting interesting. Why are you designing your network with a single point of failure - one router? You should know your skills and capabilities, not just blag this job. I do encourage you to go onto the interview and do the best you can from which you can extract what your weaknesses are and do better next time, maybe pick up a few books to reand an learn.

    Dia is one of several available here Visio | Open Source Alternative - osalt.com

    About the single point of failure..That is something the OP should address and is a good reason for him to post his proposed network here. It's kind of obvious he's starting from scratch and not thinking things through but we are here to help
    Address the single point of failure and get a better drawing. If you turned in that chicken scratch to your (hopeful) prospective boss he will give you the boot.

    No longer one point of failure, I hope you like my design now.

    The job knows I'm a CCNA, not a CCDA or DP, just want me to do a little something outside of what I fully know.

    What do you think about my design?

    Why so many routers? I know this isn't what you want to hear, but that is a horrible design. I think its time to start reading some books and labbing some stuff up.

    I just have to say this, you don't have to eat the guy clearly he's new in this and he asked for help so you have two options one is to help which i'm sure he appreciate a lot and the other is not to help which he will not mind as well but i don't understand all those bad comment about his questions then his designs.

    Every one need help at some point, he didn't commit a crime by asking for it even if it's a HUGE help he's trying and we should encourage him.

    As for me I just have to say this , i do have a ccna but i don't have a lot of experience in this so I'm sorry I can't help you much.

    Who is "eating the guy up"? Everyone has told him he's in over his head and needs to do some research. I don't think thats overly harsh.

    Your diagram looks just like one I'd expect from a newly minted CCNA. A gripe I have about the CCNA books is that they teach you to segment by function rather than location. This helps explain VLANs, but actual production networks aren't designed like this. For user subnets, you want to localize subnets and switches by location. You want to localize layer 2 traffic. You don't want a host within a vlan passing traffic across your core. You should have a DMZ or some other segmented network for all of your server traffic. And I hope that that network isn't using 5 separate mainframes lol.

    A key concept in network design is Core/Distribution/Access. Think of it like a tree. You have your big core routers at the center, your distribution routers, and then your access switches (users hang off access) And remember, redundancy redundancy redundancy. Each of your routers/switches should have 2 up-links to 2 separate devices. I could go in more depth here but I think this is something you have to research yourself before I start to write a book.

    Your requirements lists 500 users. I didn't see anything about servers, etc. I think he wants you to practice your subnetting as well so keep that in mind.

    You might want to take into consideration port density. Also, Cisco does make a few other products then the ones normally used in a home CCNA lab. You might want to check into other product lines to better serve your requirements. Good luck!

    A 2651XM couldn't handle my home network -- so the only way those 2600XMs would work in your design would be at night when no one was using the network.

    You might want to consider using current hardware -- unless it was stated that the network will be built from hardware bought on eBay.

    You may want to hit up the Cisco Web Site and check out router & switch product pages to find out what the current devices available are....

    These Guides should also be reasonably current....
    Cisco Catalyst Switch Guide PDF
    http://www.cisco.com/en/US/prod/swit...cd805f0955.pdf

    Cisco Router Guide PDF
    http://www.cisco.com/en/US/prod/coll...cd8019dc1f.pdf

    The Cisco Partner Central Portable Product Sheets include some of the older devices -- and may not have been updated yet for the newer hardware like the ISR G2s -- but you you can get a quick overall comparison of performance (and capacity) of the various devices.

    Portable Product Sheets - Partner Central
    Router Performance, Switch Performance, Router Memory, Modules Cross Reference, etc

    Good point -- current hardware AND standard network design practices. A picture is worth a 1000 words.....

    Cisco Design Zone: Design Zone/SRND - Main Page - Cisco Systems

    You can follow the View All Design Guides link there if you want to "shop" all the available designs.

    These pictures are from the Enterprise Campus 3.0 Architecture -- the collapsed core (which is probably your best bet with just 500 users in one location) and the standard impressive enterprise multi-node core that all CCNPs hopefully will get to know and admin and manage and love.








    If you drink a beer or two and ponder those diagrams you may notice they are just slightly more complex than what you should have started with (and remembered) from the CCNA --

    I was jsut going to say, if you have 100 IP cameras, you don't want to use 2950-24 switches. 3560-48 with PoE is probably what you want. And like Mike said, the 2600XM series won't work. Plus, if all of this is in the same building, then use ethernet for the backbone and not serial links. Get a 'core switch' or two and build out from there.

    If you need help deciphering some of the icons used in the drawings, you can download a printable reference pdf file on the Cisco Network Topology Icons web page:
    Network Topology Icons - Cisco Systems

    It's that "Featured Item" on the right side of that page.

    Yeah, that is really cool and gets away from the default blue router icons. I'm actually thinking of redoing my network drawings using the black and white icons. That'll give me a reason to review documentation and it'll look cool to display!
