1.8k members in the gns3 community. I need to setup a GNS3 on the cloud so multiple people can access it. I saw that there was a you tube tutorial on how to host it on Azure but unfortunately there is a problem with having QEMU images on Azure. Huawei eNSP Configurations. Huawei eNSP is the Network Simulator of Huawei.With Huawei eNSP, you can practice with Huawei Routers and Switches, you can gain hands on experience on Huawei devices.In Huawei Labs Page, you will find many Huawei Configurations with Huawei eNSP.The configurations on this page are also use for Huawei Configuration Course.So, you can watch also the video course of.
- The GNS3 Setup wizard displays. Click Next to start the installation. GNS3 is free open source software distributed under the GNU General Public License Version 3. Read the license agreement, and if you agree with the contents, click the I Agree button to continue the installation. Select the Start Menu folder for the GNS3.
- Download the IOS.bin image from Internet. To use a specific Cisco IOS image, firstly you should.
- 2- Huawei's Simulator is already installed and GNS is as well on my laptop. 3- I want integration of both simulators (GNS3 and eNSP) on VMware so that i can perform a simple lab with Cisco router and a Huawei router. 4- Attached is the file which shows the task objective. Skills: Cisco, Network Administration, Software Development, VMware.

What is Multicast MAC Address?
As you know, a MAC address consist of 48 bits. And these 48 bits are divided into two as vendor code and host code. The first part, vendor code is given by the device vendor. It shows the manufacturer of the device. The second part, host code identifies the device within the other devices of that vendor. Thare are also some specific MAC addresses used in Multicast technology. These are Multicast MAC Addresses. So, what is a Multicast MAC address?
Multicast MACs starts with a fised part as 0100:5e. For one MAC address, only the last 23 bits of that MAC address is used to produce this Multicast MAC. The first 25 is fixed . The fixed part is 0100:5e (00000001:00000000:010111110:0 … ).
In this lesson, we will explain what is a Multicast MAC Address with an example. We will learn how to create these MACs and which Multicast IP addresses are using this same Media Access Control Address.
You can visit also Multicast Quizes page, to test yourself on Multicast Lessons.
Lets explain this usage with an example.
For our example, we have a Multicast IP Address 22.214.171.124. Let’s find the Multicast MAC of this ip address and the other Multicast IP Addresses which use the same MAC address. Because, there are 32 Multicast IP addresses that corresponds to a Multicast MAC Address.
Here, we have 4 steps to produce this MAC address. These steps are given below:
1)Firstly, let’s write our ip address in binary format:
126.96.36.199 = 11100000.11111111.00000000.00000001 (32 bits)
2) Then, we let’s get the last 23 bits of this binary ip address :
3) We will take the fixed part of the Multicast MACs like below and we will write it in binary format. It is 25 bits.
0100:5e = 00000001:00000000:010111110:0
4) Lastly, we will combine the fixed 25 bits with the last 23 bits of the multicast ip to create our Multicat MAC Address :
00000001:00000000:01011110:01111111.00000000.00000001 = 01:00:5e:7F:00:01
For Multicast IP Address, the first 4 bits are fixed, these first four bits are 1110. The last 23 bits are used for Multicast MAC Address. And the remainning 5 bits in the middle can be any value. So, 2^5, you can create 32 different IP address with this changable area.
For our example, the Multicast IP addresses that share the same Multicast MAC Address are showed below. Here, with the 5th, 6th, 7th, 8th and 9th bits, 32 different Multicast IP Addresses can be written.

For example like 188.8.131.52 multicast ip address, 184.108.40.206,220.127.116.11, 18.104.22.168 ip addresses will also use the same MAC that we have produced. This is tru for all these 32 ip addresses. For another Multicast MAC, there are another 32 ip addresses certainly.

In this lesson, we have learned an important lesson of multicast technology. We have talked about mac addresses used in multicast world and the 32 same ip addresses that is used with the same mac addresses.
