Dynamips - Lab share

JVE

Hello, now that I got my dynamips working and am really loving this thing!! Was wondering, do any of you that use it have any lab configs to share? I am sure once I get the hang of it, I will be able to set up my own, but if you guys can share some of your files that would be great.

Or at least answer me this question. It seems by default the Serial 1/0 on the routers are connected, but is anything else? How do you make like the ethernets to connect, if they already are and I just have not tried it, then please correct me but i would love to have this thing do what i want. I have a 64 bit processor with 4GB of RAM so i am not hurting for resources. Thanks in advance, and I love the dynamips thing. Boson was killing me with the lack of commands and functions.

JVE

ok, i got it all figured out. It helps when you read i think!

But one thing for the life of me, how do you determine the idle pc value for the image you are running? where do you determine that?

romain

Do you know "show version" command ?

JVE

yes, i do? That does not give you the value though, if that is what you are getting at. I did figure out my problem, a guy on another problem kindly explained I had an older version of the executable. So now I am running cool, and I have a mock lab - with real IOS images, of 5 routers, a Frame Relay switch, and a switch. You can create I think up to 11 routers without it bogging down your machine. This program is awesome, for all you sim people out there, this is as close to you will get without having to buy any equipment! Very nice

Hi JVE. How many routers you can run? On my machine (2600+@1GB RAM) I can run 3 routers, and 4th one makes CLI responses very slow (not comfortable).
I would like to know it becouse I want to run more than 3R, and I am looking for new machine.

Would you like to interconnect dynamips labs with hamachi (VPN) ?

I never use dynamips before.

But if your concern is memory usuage. It's probably as easy as pressing ctrl+alt+del to check how much ram each dynamips router use.

JVE

Hey, I have run 7 routers without problem, although I have some labs that have 9 routers in them. The key is the idlepc value, which makes the CPU load come way down. Here is my config for you to use, which works very nice for studying for the CCNP - you will need your own IOS image though.

In this lab, Router 1 and Router 5 connect to an ethernet lan segment in which they are "attached", also Router 1,2, and 3 are connected via a Frame switch, as well as Router 3 and 4 being connected to a different ethernet segment, which is the Lan 1 segment. This stuff becomes real easy to play with and change to set up labs in any way you like once you get the hang of it. Also unzip your IOS image with Winrar and it loads the image very fast instead of waiting for it to uncompress.

Is dynamips freeware?

where's best place to get it?

JVE

Yes it is free! You can not beat this simulator with anything on the market except for having the real equipment, which in my opinion you dont really need if you have touched routers before. I have the Boson CCNP final version and it is ok, but not enough in my view. With that software, I was able to ping from one side of a connection, but not from the other and I just think the software stinks. I started using Dynamips - and really the dynagen and I have not looked back. I promise you with that software, I will get my CCIE and be fully prepared. In fact, listed below is a CCIE lab that is mock conditions for the real lab. Although you need to practice with a real 3550 which this software can not emulate. Here is the link to download

sorry to asking some noob question, coz this is my first time to heard Dynamips Cisco router emulator. Last time i use Boson netsim and many things cannot simulate. Then i have invest some $$ on the real router like 2600, 2500..

my question is , this Dynamips Cisco router emulator is it can replace all my router ??? with the actual CLI enivironment ? and different kind of IOS..... by the way, wat is the model they support ?


Thanks in advance for reply

blackzone

I never used it before. I tried to use it but it require IOS image for 3620, 3640, 7200 from Cisco router which I don't have.

Dynamips is like vmware and virtual PC which simulate the hardware of a computer, you need to provide the IOS to it.

william_yeo

i have put the IOS in the correct directory, but i duno how to teach the system to boot the correct IOS and set the RAM size for it.....

JVE

They just released a brand new version, which supports 3600 series routers as well, and yes, the command line is real, because it uses real IOS, which as stated, you have to place yourself. Install dynamips and dynagen and if you use Windows, also winpcap - beta release 4. This allows you to allow it to talk to real networks. In my view, you dont need anything else but this program. They are working on an ISDN emulator which I would think will be ready in about a month or so, which is right when I will need it, for BCRAN!

With your real routers you have, you can have dynamips communicate with them and it will work as if it were a real router in your lab, very nice piece of software these guys made, and it is free.

william_yeo

finally it's working.... but i not really sure bout the configuration...... for example.. how to create a back2back connection for 2 routers ???

Nice! I'll have to find the time to upgrade and give it a try!

You kids have it so easy these days! Back in the old days you either had to build an expensive home lab or rent rack time. Yep.... a lot has changed in the last 2 months!

Ching01

Last night I design my dynamips home lab, so I woke up early around 6 am couldn't wait to configure IS-IS. I used 10 routers and 3 real routers and wow this thing rocks.

I am using 12.3 c7200 but It gives me IS-IS is not supported so I decided to use 12.2 c7200.

I mixed my lab with FR p-m and point-to-point , Also set up a core backbone all in L2 .

I finish my lab excercise around 8 hours, I thought IS-IS is difficult and using this tool I could say it is very easy.

Next top BGP, I hope I could remember what I have learned and read in sybex CCNP.

wow ~~ it works with actual routers !? how it work ? mind to briefly explain........ sorry for noob question..

Ching01

If you installed Dynamips/Dynagen there is a folder name DOCS just open it and read it, so that you know how Dynamips works.

william_yeo

this is really a good VM for routers !!! best of the best.... new version was released ! please check it out

one of the poor things, is that this VM does not support for trunking.....

" Version 0.6.0 released - The primary new feature is support for the NM-16ESW module Chris just added to 0.2.6-RC1. See the readme for other features and bugfixes"

Dear JVE,

Thnx a lot for the CCIE Lab net file config. But i am facing a problem when i try to open it. Its showing "error- invlaid npe type". I tried changing the npe type still no use. its the same. Can u please help me with the same.

Thanks in advance,
