Replicate vMX

‎10-22-2019 09:54 AM

Having purchased 2 x servers to run vMX on and BOTH servers failing to even install the base Linux OS, I have given up on that front for vMX.

 

Given that I only really need this for taking exams (studying for JNCIE) does any one else have any recommendations of where I can practice configurations and see readouts etc etc?

Juniper education has a free public lab out on the vLabs site.  you can spin up machines or pre done topologies for your studies by creating and account here.

Also check out the Juniper sponsored NRE labs for free infrastructure around automation tooling.

I've put my lab configs up on my blog if that helps?

I was in the same place last year

Most stable reliable, option I found was to install esxi (free version)

On this i onboarded a GNS3 VM which i assigned almost all the 64G i had availble

Within that instance I run all my vmxs

 

If you have two servers you can duplicate both setups on each and peer with them on GNS3 client (run locally)

https://docs.gns3.com/144QvvLxBT69_fv-pPHf4etc5xjdItiA_a8s8gVmSTDk/index.html - Install vmx on gns3

It may sound kludgy to run virtualization inside virtualization but having reliable snapshots are an absolute must in my experience - gns3 makes the whole process pretty painless though be advised that you will get the occaisional instability with the vmx (losing interfaces, freezing, etc) but nothing that cant be resolved with a vmx reboot, platform reboot or rollback to your snapshot. Now I would imagine that if you are running retired commercial servers you would have ECC ram and you would have a better experience than I have had, but I can't say more than that

 

Other opions are running your vmx's inside eve-ng (i preferred above to this)
also running bare inside esxi - but as I hear the networking is a pain to setup and worse to change and you will be wanting to change it for pursuing an IE

 

Hope that helps

You may find performance-mode doesn't work inside GNS3. You need performance-mode if you're testing CoS, possibly others.

 

Post the exact issues you were having, however trivial they might sound. I laboured over my setup for weeks. It was an absolute pain in the ass to get working but I got there eventually.

 

This forum helped.
