How to install GNS3 3.1.0a3 edition in Windows environment


Goal :- 

In real world, environment networks are used to test various problems in an emulation manner to diagnose the problems or for who are studying cisco studies or networking studies, it's the all-in-one best solution. All in one place in one your PC. So let's don't waste any time. Jump into the goal.


 Requirements:-

GNS3-3.1.0a3-all-in-one
GNS3.VM.VirtualBox.3.1.0a3  VM 
VirtualBox-7.2.16-174877-Win


Hello friends..!!!
Thanks participating with me my next technical blog, previously I prepared my older post for technical post, my goal is solve everything easily; anyone can understand,  simple manner to understand, here  I am explaining the technical content in clear manner, if  getting trouble to  understanding by reading, I am arranging the video solution too.. so you can  contintue the steps in a step-by-step manner. Today we will continue to learn the Gsn3 alpha edition. You can download here https://github.com/GNS3/gns3-gui/releases/download/v3.1.0a3/GNS3-3.1.0a3-all-in-one.exe
and for the virtual box link here 

https://download.virtualbox.org/virtualbox/7.2.18/VirtualBox-7.2.18-175117-Win.exe

for Virtual box image below the link

Configuring & implementation of Hub and Spoke on frame-relay networks on Cisco Routers

 Scenario

We are running the comnapy in diffrent locations to manage the better work, we need the strong network communications in different locations, so employees can access applicaitons, manage databases, and shared resourses to head office. while running the company you are selected as network engineer to manage the better production networks. For better services you advised the frame-realy WAN serive from telecommunication provider to connect the different location offices.


Objectives:

Configure the ip addresses according to below network diagram.

Configure the DLCI address. DLCI stands for Data Link Connection Identifier

Check the connectivity from all routers

configure the DCLI address hub and spoke routers

Configuring the static routes between two vendor products Like Mikrotik Router as well as Cisco Router

Introduction:-

Now a days in the in the networking industry, routing and switching are very fast-growing in the world; simultaneously, the hardware equipment is rapidly developing, but in the various types of the vendor products are not communicating with OS, scripting issues or any.. here we are look forward to communicating and developing the routes betweent the two verndor products..  Lets move farword.


Real-world Scenario:

Routing is in the real world, there is path from one network to another network. Here we observe the routing between two vendor products like Cisco router as well as Mikrotik router. Here am not using the real eqipement, by using the images, in grouping together one place in the emulator, we all know the name of the emulator like GNS3.  Here I as using  the Image of MIKROTIK CHR, and for Cisco i am using CISCO IOU image for cisco hardware.





 network addresses


10.0.1.0/30 
20.0.2.0/30
30.0.3.0/30

These are the networks, configure the ip address according the above network diagram.


Goal:

Configure the static routes between the two vendor products like Mirkotik and cisco through the emulator..


Configuration Commands :

Mikrotik R1 
/ip add add address=10.0.1.1/30 interface=ether1
/ip add add address=20.0.1.1/30 interface=ether2
/ip route add dst-add=30.0.2.0/30 gateway=10.0.1.2



Mikrotik R2
/ip add add address=10.0.1.2/30 interface=ether1
/ip add add address=30.0.2.1/30 interface=ether2
/ip route add dst-add=20.0.1.0/30 gateway=10.0.1.1

Cisco R1
ip route 10.0.1.0 255.255.255.252 20.0.1.1
ip route 30.0.2.0 255.255.255.252 10.0.1.2

Cisco R2
ip route 10.0.1.0 255.255.255.252 30.0.2.1
ip route 20.0.1.0 255.255.255.252 10.0.1.2
