Download Cisco IOS 12.4

I am really sorry for delay but its totally done. Please download document file first for information.

This is my collection of Cisco IOS for use with Dynamips.

The originals .bin files has been unzipped and renamed to .image, and recompressed with RAR to save disk space. Dynamips works better with an unzipped IOS,
the router boot faster. You need to decompress the file with WinRar, UnRar, 7Zip, etc, to obtain the .image file and store it in the image folder.

This compilation includes several IOS for PIX (IOS and ASDM) and special IOS called Pagent and Callgen.

Pagent is a set of data networking test tools, based on the Cisco IOS (Internetwork Operating System) and developed within Cisco. The test tools are included in special IOS
Pagent images.

Callgen is a set of Voice-Over-IP networking test tools, based on the Cisco IOS and developed within Cisco. The test tools are included in special IOS Callgen images.

The primary function of the Pagent and Callgen toolsets is to provide cost effective test tools to the Cisco testing community. The secondary function is to provide testing
capabilities that are not available anywhere else and can be used in customer environments. One essential function is to generate valid simulated traffic necessary for testing
networks under stress. The tools are not able to test the physical network layer and some parts of the data-link layer; that is, they can not affect frame checksums, preambles, inter
frame gap times, inject hardware failures, or transmit invalid packet sizes.

The Pagent programs are best used for testing layer 3 protocols and above; that is, emulating routing protocols, multicast, TCP sessions and HTTP sessions.

Pagent is an enhanced Cisco IOS image that contains both Advanced IP or IP Base Services and the IP traffic generation tools. Pagent generates realistic traffic and bottlenecks to
test QoS features such as IP Classification, IP Marking, and Queuing.

CallGen is a Cisco IOS-based bulk call generation tool implemented through extensions to the regular Cisco IOS image, which provides commands and utilities used to simulate
originating and terminating calls on routers and access servers.

The file "Patch for Dynamips.txt" contains the instructions for patch Dynamips (for use with Dynagen or GNS3) to use this IOS. In every folder, the TXT file includes the description of
all IOS: name, features and RAM memory in Mb.

Please download me first for check all versions and your requirement.

What is GNS3 ?

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

To provide complete and accurate simulations, GNS3 is strongly linked with:

• Dynamips, a Cisco IOS emulator.
• Dynagen, a text-based front end for Dynamips.
• Qemu, a generic and open source machine emulator and virtualizer.
• VirtualBox, a free and powerful virtualization software.

GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to study for certifications such as Cisco CCNA, CCNP, CCIP and CCIE as well as Juniper JNCIA, JNCIS and JNCIE.

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

Planning and Verification Exam Topics

Concepts and Methodologies:
There are a number of concepts and methodologies that are used in the IT and Telecommunications industry, however to name a few:
The following two methodologies are trademarks of the UK Office of Government Commerce, however have become globally recognised and adopted by a number of international organisations.

• PRINCE2 (PRojects IN Controlled Environments) and,
• ITIL (Information Technology Infrastructure Library)

The next two are Cisco propriety, which you may encounter throughout your Cisco career.

• PPDIOO (Prepare, Plan Design, Implement, Operate, Optimise) and.
• Cisco Lifecycle Services

What is CCNA?

Definition: CCNA is a popular certification in computer networking developed by Cisco Systems. Cisco created the CCNA to recognize basic competency in installation and support of medium-sized networks.
The core CCNA certification can be obtained by passing a single 90-minute written exam. The exam has no prerequisites, although Cisco and other companies offer various formal training courses to help students prepare.

Topics covered on the CCNA exam include

•LAN and WAN design (including the OSI model)

•IP addressing

•routers and routing protocols (including OSPF, EIGRP and RIP)

•VLAN (virtual LAN) and WLAN (wireless LAN)

•network security and management (including ACLs)

What is CCNP?

CCNP Certification is awarded by Cisco Systems® and signifies the competency achieved in installing, configuring, and operating LAN, WAN, and dial access services in medium to large networks (500+ nodes or more), including use of these protocols: IP, IGRP, EIGRP, IS-IS, BGP, OSPF, Serial, Frame Relay, IP RIP, VLANs, RIP, Ethernet, Access Lists.  CCNA is a pre-requisite for CCNP certification. The CCNP certification is awarded after successful completion of the following 3 exams:

1. Building Scalable Cisco Internetworks 640-901

2. Building Cisco^® Multilayer Switched Networks, Exam 640-604

4. Cisco^® Internetwork Troubleshooting, Exam 640-606

Alternatively, you can pass only two exams. Please see CCNP preparation page for details.
