The choice of making GNS3 useable without the need of a VM and multi platform offers a powerful solution to users even with low resources computers but increases the attack surface. This document aims to cover the possible attack vectors and security considerations every good administrator should consider before installing/using GNS3. Although our focus is not currently on application security, we do encourage contributions of this nature to the project, and understand this is an extremely important part of our the application’s development. We have prioritised making GNS3 as user friendly as possible, as opposed to hardening the application against every possible security threat.

GNS3 is designed for allowing full control via the GUI.

The demographic of GNS3 users is very broad, ranging from networking students, through to systems administrators in large corporations. Users of GNS3 need to bear in mind that it is a tool designed to be used for experimentation/learning, not for managing Virtual Machines or appliances in a production environment.

Configure GNS3 to use an additional remote server.

I have demonstrated a small GNS3 lab, how to configure HSRP hot standby routing protocol on gns3 IOU cisco image, Please do let me know if you have any question regarding my lab. When you right click connection link between devices in GNS3, there is an option to start Wireshark network analyzer.įirst of all, Please see the ICMP capturing, as you see P1 source 10.10.10.5 uses R1 to reach PC2 destination 172.16.10.5 The reason PC1 chose the router R1, R1 is acting an active router.īelow this line, the picture shows HSRP capturing Īs I have mentioned on top of the page, We have used HSRP V1! How can you understand HSRP version?ġIssue on router R1 or R2 - show standby allĢ)The picture shows destination address 224.0.0.2 multicast address ( which means HSRP V1 ) Let’s see HOW this HSRP and ICMP traffic look like in Wireshark ( Network Monitoring Software) I have turned off e0/0,e0/1 interfaces, Standby router took over active router role from R1 to 10.10.10.2 IP address.

Virtual IP 10.10.10.10/24 ( Default gateway for PC1 )Īs you see we can able to ping PC2 ( 172.16.10.5/24) and traceroute shows ICMP packets use 10.10.10.1 which means We have set standby 1 preempt and standby 1 priority 130 commands on R1.

R2 is a standby router with Ip address 10.10.10.2 / 24.

R1 is acting an Active router with IP address 10.10.10.1 /24.

Let’s issue HSRP troubleshoot command here Same configuration as R1 for Routing protocol and also for interface ethernet 0/0 and 0/1 are configured with. Here is the basic EIGRP configuration for our lab, we have allowed an IP address on the network by issuing network 0.0.0.0. We will shut down R1 and after 10 seconds of HSRP hold time R2 will take over active router role, and the ICMP traffic will go through R2. P1 will ping to PC2 1st R1 will act as an active router and R2 will be standby router.

This Lab will show you how to configure basic HSRP on GNS3 IOU image and Capture the packets via Wireshark*. V2 (mac address multicast address 224.0.0.102)ĭefault hello interval 3sec & hold time 10sec.V1 (mac address multicast address 224.0.0.2 ).It is a Cisco proprietary protocol and using an Active router and Standby Router. HSRP stands Hot Standby Router Protocol, gives us default redundancy, load balance, and fault tolerance.
