Linux Mint 12 : How to install dynamips and gns3 ( Cisco Router Emulator )

Here’s an explanation of how to install dynamips and gns3 on Linux Mint 12.

# uname -ri 3.0.0-15-generic x86_64 # tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Linux Mint 12 Lisa"

[ install dynamips and gns3 ]

dynamips is Cisco Router emulator and gns3 is GUI tool for dynamips.

# apt-get install -y dynamips gns3

[ initial setup ]

start gns3

$ gns3 &

do step1 ( configure working directory ) and then step2 ( load IOS )

step1 ( click OK. default settings )

step2

select the IOS image you want to run.

I used c3640-jk9s-mz.124-13a.bin.

click “Save”

drag and drop “Router c3600” icon like this.

start c3600

configure Idle PC

By default , the dynamips process uses around 100% CPU consumption.

# top -b -n 1 | grep dynamips 25472 hattori   20   0  363m 185m  65m S   99  1.5   3:17.27 dynamips

To reduce CPU consumption

select Router icon , right-click , Idle PC

Dynampis will calculate an appropriate Idle PC values.

Click “Apply”

After configuring Idle PC values.

# top -b -n 1 | grep dynamips 25472 hattori   20   0  363m 185m  65m S    8  1.5   6:57.80 dynamips

CPU consumption is 8%.

Configuration file is stored under .gns/ directory. ( gns3.ini file )

# head -5 /home/hattori/.gns3/gns3.ini [GNS3] version=1795 lang=en project_startup=true relative_paths=true

Ubuntu 10.10 Server : How to run Cisco IOS 15.1 on dynamips (GNS3)

Here’s how to fly an ISO 15.1 on dynamips.

# tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Ubuntu 10.10" # uname -r 2.6.35-28-server # dynamips --version Cisco Router Simulation Platform (version 0.2.8-RC2-amd64) # gns3 --version gns3 0.7

[ prepare an IOS for Cisco 7206VXR ]

I used c7200-adventerprisek9-mz.151-4.M.bin

plz note that not c7200p images! In my testing , these images don’t seem to boot.

[ configure GNS3 to fly IOS 15.1 ]

select c7200-adventerprisek9-mz.151-4.M.bin as a boot ISO image


If you haven’t installed dynamips , just tyep

# apt-get install gns3 dynamips

General:

Midplane is vxr and NPE is npe-400.


Memories n’ disks setting is default.




add a module on slot1

[ fly R1(c7200) via GNS3 ]

calculate n’ set IDLEPC value.


IOS 15.1 is running

Cisco router emulator : how to use dynamips n’ GNS3 on Ubuntu10.04 64bit

root@hat1:~# cat /etc/lsb-release | grep -i description
DISTRIB_DESCRIPTION="Ubuntu 10.04.1 LTS"

root@hat1:~# apt-cache search dynamips
dynagen - Cisco 7200 Router Emulator Command Line Interface
dynamips - Cisco 7200/3600/3725/3745/2600/1700 Router Emulator
gns3 - graphical network simulator

- install dynamips n’ gns3

CLIで操作したい場合は dynagen をインストール。
GUIで操作したいので、 Ciscoエミュレータの dynamips と フロントエンドGUI の GNS3 をインストール。

root@hat1:~# apt-get install dynamips gns3

- GNS3を起動

アプリケーション -> 教養・教育 -> GNS3



Step1 で dynamips がインストールディレクトリなど全般設定をする。
apt-get で dynamips , gns3 をインストールしている場合、デフォルト設定でOK


IOSを選択


ラボの作成

file -> New project


トポロジーを作成

node types のアイコンをドラッグn’ドロップで中央にもっていく
適当にリンクを追加


起動


こんな感じ


idlepc の設定

デフォルトだとCPU100% 使用するので idlepc 値を設定する。

2つルータを起動sいているので、CPUがほぼ200%

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
2813 root      20   0  551m 144m  71m S  197  1.9  13:31.43 dynamips

ルータアイコン右クリック -> IDLE PC


IDLE PC 設定後のCPU使用率。さがった。

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
2813 root      20   0  551m 144m  71m S   21  1.9  17:11.02 dynamips

停止は、ルータを suspend 。
設定の保存: ネットワークファイルを名前を付けて保存(アイコン)
設定の復旧: ネットワークファイルを開く ( アイコン ) -> *.net ファイルを指定
