CCNP RS : HOME LAB SETUP

Dec 21, 2011 5:16 AM

Hello to all


I am preparing for CCNP-RS. I am planing to setup a reasonable lab for CCNP studies at home. I have done with Packet Tracer and GNS3. Packet Tracer is good for CCNA but not enough for CCNP. GNS3 brings my laptop [Lenovo SL500 T9400 2.53 / 2.53 , Centrino2/ 6MB-L3/ 4GB-DDR2/ W7u-64BIT] on fire "extreem hot ".

Need advise !!


Thanks for reading

    hi Mintu7,

    PT is definitely just for CCNA level. Are you using idle pc with your actual GNS setup?

    +1 on the idle pc settings that need to be spot on. PacketTracer is OK for the basic stuff, but if you want to get more advanced, you will likely runinto a brick wall and get very frustrated with it's limitations.

     

    Good luck

    I used GNS for most of my CCNP prep although I used 4 switches for the SWITCH exam.  If you cannot use real switches, look into renting rack time. 

     

    Optimizing your idle-pc value is key to getting GNS to work.  Likewise, you need a GNS friendly router.  For me, the 3725 works best.  I have always had problems with the 2600's.

    Hi,

     

     

    Your config is best for CCNP no need to  update anything.

     

    Thanks & Regards,

    You could also consider building a physical lab, I have the TSHOOT setup at home.  GNS3 is great but I prefer to use real kit aswell to see how stuff reacts when you configure it.

     

    My wife complains like mad when everything is on with the fans howling, and it's not exactly friendly on the electricity bill   More fun than dragging icons around though.

    Re: CCNP RS : LAB SETUP

    Yeah it's frustrating buing kit off Ebay...you have to be really thorough while reading the ads to make sure you know exactly what you are buying, there are a lot of scammers on there.  I've never had any trouble with GNS3 crashing, my big concern is trusting that the simulation will act exactly as a real router would as I've had some odd results when doing PBR.

     

    My lab now consists of;

     

    1x ASA5520

    1x Cisco3825

    1x Cisco2811

    4x Cisco1841

    1x Cisco3640

    2x WS-C3750-48P

    2x WS-C2950-24

     

    IP Phones and some WLAN kit is next on my shopping list, I'm also in the process of building a couple of servers.

    Re: CCNP RS : LAB SETUP

    What router models have you tried with GNS?  Once I found one that worked with GNS, I had no problems keeping GNS up and running for days.

     

    Not trying to steer you away from real gear, its just that I have had great results using GNS for CCNP and CCIP prep.

    The 3725 ended up working best for me.  The 1700 and 2600 series gave me the same problems you are seeing.

     

    Im using the 3725 advanced ip services 12.4 15T14 image.

    Hot is good for Winter, right?

     

    Generally, running GNS3 on laptops might not be good idea, unless your have i5 or i7;  your Mobile Dual Core 2.51 GHz should pull some GNS routers; how many? not sure.

     

    Stop all unecassary processes;

    exclude Antivrus scanning for GNS3 folder and files, Cisco IOS, etc

    what is your CPU usage with just 1 gns3 rotuer?

    How much free RAM u got? Before running gns and with?

     

    2600s and 3725s routers are OK for gns, just have to find a good image that runs well (not all do and must be uncompressed);

     

     

    see tips and tricks for gns3: https://learningnetwork.cisco.com/thread/23445

    Re: CCNP RS : LAB SETUP

    I have run 10+ routers on Win7 64 bit laptop with 4GB RAM and Core-2 Duo processor.

     

    As Martion mentioned, make sure the IOS image is uncompressed.  Likewise, I have 2 Hypervisors set up.  I use the 3725 router with 128MB RAM.  (See photo for my settings.)
