What is eve ng internet access and how its works
·
The Community Edition of the excellent network simulation program eve
ng internet access supports running a variety of network nodes (ASAv,
NX-OSv, CSR1000v, Arista vEOS, and so on). On their website, there is a lengthy
list of supported images.
·
I used it to get ready for the CCIE R&S switching exam, and I'm
currently using it to get ready for the CCIE Datacenter exam. However, when I
used it for the first time, two things bothered me:
·
No NAT cloud is available to help connect devices to the Internet quickly
(take the example of creating a Linux image and adding it to eve ng internet access before realizing you
forgot to install something).
·
Links cannot be connected while the devices are running; you must turn
them off first. The Professional edition has both of these. Although the
hot-add feature appears to have already been included to the community edition,
it appears that the author chose to fork eve ng windows client on their own.
·
Make a compact lab; in this illustration, all that is needed is a Linux
node running a linux image. Add a network next (+ icon at the top of the
screen, then network), give it a name, and then choose the Cloud9 interface
from the type dropdown.
·
When you do this, a tiny cloud symbol will appear in your lab topology,
allowing you to connect the topology's nodes to the Internet. There is no
restriction on the number of nodes you can connect, and there are an unlimited
number of Ethernet connections available.
·
You can utilize the tools provided by eve ng windows client to
interact with virtual objects and connect them to other virtual or physical
objects. Numerous of its qualities significantly improve usability,
reusability, manageability, interconnection, distribution, and afterwards the capacity
to comprehend and share topologies, work, thoughts, concepts, or just
"labs."
·
This could simply mean that it will take less money and time to set up
what you need, or it could mean that it will make it possible for you to
complete activities that you never would have thought were so simple.
·
It can be used to research various technologies. You can gain knowledge
on both general technology issues and vendor-specific ones. You can experiment
with new technologies like SDN and network automation.
·
It can be used to simulate business networks and evaluate modifications
before implementing them. For clients, you can produce proof of ideas. By
simulating network problems and, for instance, using Wireshark to examine
packets, you can troubleshoot them.
·
It can be used for much more than just networking; examples include
testing software on simulated networks, checking for general security flaws,
and system engineering tasks like testing LDAP and AD servers.
