Configuring and implementation of HSRP on GNS3 with live link failure simulation

Hot Standby Router Protocol 

Introduction:

HSRP is  routing protocol HSRP stands for HOT STANDBY ROUTER PROTOCOL, it provides the network redundancy for the IP networks, it’s a dynamic router redundancy mechanism. It’s a Cisco proprietary protocol which provides redundancy for local subnets. HSRP has a good feature like we configure two or more routers as a standby routers and only single router works as active router. Active router responsible for forwarding the traffic. If the active router fails,

 standby router will takeover the responsibilities for the active router. HSRP offers unique advantages and some limitations. This protocol reveals deep dive into the functions, benefits, and real-world data, HSRP to help you understand the best suited for the real network needs. HSRP acts as a backup plan ensure that if the primary router fails another seamlessly takes over the responsibility of the primary router. It is a redundancy protocol that ensures high availability in network environment.

 It has 2-versions like version 1 & 2

 version 1 : The messages are multicast at 224.0.0.2 and uses the UDP port 1985. This version allows group number range from 0 to 255. 

version 2 : The messages are multicast at 224.0.0.102 and uses the UDP port 1985. This version allows group number range from 0 to 4095.

Capability	Version 1	Version 2
Hello timer units	Seconds	Milliseconds
Supports both IPv4 and IPv6	No (only IPv4)	Yes
Number of groups supported	256 (from 0 to 255)	4096 (from 0 to 4095)
Virtual MAC (-- or --- is the HSRP group number in HEX)	0000.0C07.AC--	0000.0C9F.F---
Multicast address	224.0.0.2	224.0.0.102

 Here in the video solution I explained the link failure simulation only there you can edit the timers and preempt..

That is based on the delaying the pinging..

Hopeful this very useful I think

How to install & configuring the Mikrotik CHR in GNS3 VM 1.5.2

How to install & configuring the Mikrotik CHR in GNS3 VM 1.5.2

 

Requirements

GNS3-1.5.2-all-in-one.exe

Gns3 1.5.2 VM virtual box image (or) VMware image

Mikrotik CHR image

Mikrotik-CHR.gns3a

Virtualbox.exe

First you  can install these all above mentioned files and run the Gns3 it will asking for conformation Gns3 or VMware to run the VM, there you can choose you choice.

Here I am selecting the Virtualbox  because it’s free. There am selecting the Virtual box  to run the GNS3VM. Then the Virtual box will run automatically, wait for some time it will boot. After some time it will shows the window in the GNS3VM the version of the GNS3.

Then you can open the GNS3 and choose import appliance, it will asking the GNS3-CHR.gns3a file, show that file it will open an window there you can appear the message file missing, there you choose the create new version, after that you choose your  downloaded file of Mikrotik-CHR.img file, then click next and after that you can fallow the instructions and click on finish. You see the message there Mikrotik CHR installed successfully. For modification of network adaptors you can edit you manner.

For more clarification see my video solution, it will explain  cleary..

All the best..

How to get the Cisco IOU License using Gns3 1.5.2

Hello friends..!!!

Today we will discuss and run the cisco IOU license using the GNS3 earlier version of Gns3 1.5.2

any how Gns3 is the very advanced tool for  network testers..

As per my experience i am very struggled to run the IOU for the first time. firstly i run only IOS in Gns3 at local computer, but switching purpose i am very confused to run switches in Gns3, but Gns3 developed in Gns3VM. Gns3 introduced the virtual box, VMware, Esxi.

You can download the gns3 at website www.gns3.com,

Any how we will come to discuss the getting the cisco IOU license..

we required these files.

Gns3 VM 1.5.2

Gns3 1.5.2.exe

CiscoIOUKeygen.py

winSCP.exe

after that we required these commands...

chmod +x CiscoIOUKeygen.py

echo -ne \\x1\\x0\\x0\\x0 > /etc/hostid

echo -ne \\x1\\x0\\x0\\x0 > /etc/ioukey

sudo echo hostid = 0000001
sudo echo hostname = gns3-iouvm
sudo echo ioukey = 3d9

sudo apt-get install python-minimal
