Packet Tracer offers an effective, interactive environment for learning networking concepts and protocols. Most importantly, Packet Tracer helps students and instructors create their own virtual “network worlds” for exploration, experimentation, and explanation of networking concepts and technologies.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
Yes you can do everything you need with PT. You can also use gns3 for routing. ... Packet tracer is enough for the CCENT v3 exam, but you need at least GNS3 for the CCNA v3 exam.
VIRL comes in two different editions – Personal Edition and Academic Edition. Both have the same features except the Academic Edition is cheaper. At the time of writing, Academic Edition costs $79.
Both the features are better with GNS3 and EVE-NG when compared with VIRL. While comparing GNS3 vs EVE-NG, we find that GNS3 is a free, open-source community that has built a well-documented piece of software.

This is commercial software, and a personal license costs $199 a year.
Cisco Packet Tracer
You might consider setting yourself the goal of taking the exam within the next 6 months and budget your study time and social engagements accordingly.
Cisco now allow you to access Cisco VIRL IOSv, IOSvL2, ASAv and many other devices for free using Cisco dCloud or Cisco DevNet. That's right. You don't just have one choice, but two.
For those not in the know, Cisco's Virtual Internet Routing Lab (VIRL) is a network design and simulation environment that includes a graphical user interface, much like GNS3, to build virtual network topologies. ...
IOSv is an implementation of Cisco IOS running as a full virtual machine on a hypervisor. IOSv supports up to 15 Gigabit Ethernet interface. IOSv provides full layer-3 control-plane and data-plane functionality.
VIRL is Cisco's powerful network simulation platform. ... Easily create connections to actual networking equipment by extending your lab to physical and virtual networking devices. VIRL is your complete network simulation platform for testing, training, and learning.
GNS3 allows you take Routers CLI. It doesn't allow to take CLI of switch or any End User Devices. 2.
IOSvL2 is an implementation of Cisco IOS Layer-2 switching code (based on the DSGS code branch) running as a full virtual machine on a hypervisor. IOSv supports up to 16 Gigabit Ethernet interface (one reserved for management purposes)
Graphical Network Simulator-3 (shortened to GNS3) is a network software emulator first released in 2008. It allows the combination of virtual and real devices, used to simulate complex networks. It uses Dynamips emulation software to simulate Cisco IOS.
Installing and importing Cisco IOS in GNS3
If your work has a bunch of cisco gear you can copy the IOS from the hardware and use it in GNS3. Similarly, if they have any service contracts with cisco, you can just download them from cisco.com.
You will see that a layer 3 switch in GNS3 console has been added. Drag it to the work view area. Right-click layer 3 switch (ESW1) and select Start to start it. Once it is started, select and right-click again it and select Console to open its console.
GNS3 support many switching options - they range from unmanaged switches, to Cisco IOS switches, to Datacenter Nexus switches, to Etherswitch modules and then emerging technologies such as OpenFlow and SDN. ... This is the official Cisco way of emulating a switch.
EtherSwitch Network Module (ESW)—ESW modules are configured by Router IOS. These modules do not run separate software. It is integrated into the host router IOS. You can create VLANs, configure VLANs, spanning tree, and VTP from the host router.
By using the vIOS-L2 image, you can use many switching features such as Etherchannel, DTP, HSRP, Port Security, VLAN Routing, Switchport, 802.
Cisco IOS on Unix, also known as Cisco IOU, is released for internal Cisco use only. IOU permits to run IOS natively on x86 platform while GNS3 must emulate the whole hardware.
SSH to the EVE to obtain cli access, and create temporary directory abc. Upload original Cisco image binary file to temporary directory abc. The best for upload is FileZilla or WinSCP. Using EVE CLI, uncompress original image.
