GNS3 in Live CD

What is GNS3 ?

GNS3 is a graphical network simulator that allows simulation of complex networks.

To allow complete simulations, GNS3 is strongly linked with :

* Dynamips, the core program that allows Cisco IOS emulation.
* Dynagen, a text-based front-end for Dynamips.
* Pemu, a Cisco PIX firewall emulator based on Qemu.

GNS3 is an excellent complementary tool to real labs for Cisco network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP or CCIE.

It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers.

This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.

Features overview

* Design of high quality and complex network topologies.
* Emulation of many Cisco router platforms and PIX firewalls.
* Simulation of simple Ethernet, ATM and Frame Relay switches.
* Connection of the simulated network to the real world!
* Packet capture using Wireshark.

Important notice: users have to provide their own Cisco IOS to use with GNS3.

How to configure Citycell Zoom USB Modem for Linux

This is the configuration of the CDMA USB modem provided by citycell with their zoom connection to use in my linux distro (Centos 4.4) - Heres how to-

Attach the modem with your pc/laptop, Restart your computer

1. Now check with dmesg if it has been successfully probed
dmesg | grep tty

You will get some output like this

[ 2315.412106] usbcore: registered new interface driver usbserial
[ 2315.412508] drivers/usb/serial/usb-serial.c: USB Serial support registered for generic
[ 2315.461938] usbcore: registered new interface driver usbserial_generic
[ 2315.461945] drivers/usb/serial/usb-serial.c: USB Serial Driver core
[ 2315.480382] drivers/usb/serial/usb-serial.c: USB Serial support registered for pl2303
[ 2315.480414] pl2303 2-6:1.0: pl2303 converter detected
[ 2315.480608] usb 2-6: pl2303 converter now attached to ttyUSB0 (You may get it as ttyACM0, if you get it as a /dev/usb/ttyACM0)

if you didn’t get the message follow the steps 3 and 4 and back to step 1

2. Now configure your wvdial.conf as shown here.
vi /etc/wvdial.conf

[Modem0]
Modem = /dev/ttyUSB0 or /dev/usb/ttyACM0
Baud = 230400
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
[Dialer cdma]
Username = waps
Password = waps
Phone = #777
Stupid Mode = 1
Inherits = Modem0

Now save this file

If you Successfully complete the steps 1 and 2 no need follow steps 3 and 4

3. check if the USB device is detected properly
cat /proc/bus/usb/devices

you will get some output like this

…..
…..
T: Bus=02 Lev=01 Prnt=01 Port=05 Cnt=02 Dev#= 4 Spd=12 MxCh= 0

MPLS BENEFITS

1) faster switching then IP as IP Forwarding is based on IP routing table search each address is 4 octets length and can cause some time to calculate

2) Core free from BGP as the MPLS is based on label switching there is no need any more for core routers to participate in the BGP network and only Edge routers need to be BGP aware. this is a huge memory and utilization saving.

3) MPLS TE Traffic Engineering is one of the major benefits as it is allowing you to have better path selections and it have a very good mechanism called FRR Fast ReRouting and this is allowing to re-route traffic from and unavailable router in a really fast speed of less then 50ms, and this is allowing us to build a stable and reliable Data and VoIP Network as you know less then 50ms loss will still keep the Voice Call Up, if it is more then that the call will be dropped. so this feature allows us in a good planed network to give us near PSTN solution.

4) MPLS VPN is another major benefit as it is reducing manageability and introducing simplicity to the client. before if the client wanted to create a VPN for his offices network he needed to either create tunnels between all his offices creating a lot of configuration and complex design when there are more then 4 branches or he needed to ask the provider to create all this VPN's and relay on his network design. but with MPLS VPN he simply need to make a Connection between his Customer Edge Router and Provider Edge Router.
