Back on the CCNA bandwagon…with esxi March 6, 2019

Ok so its been a while since i talked about networking (the computer kind not the people kind), and im a little bit excited to say the least.

Im current going through the icnd1 book and have almost completed it, but rather than use gns3 via a virtualised linux guest on my esxi server i managed to get Cisco’s ios xrv 1000 working properly.

Basically my current topology is pretty limited (just 2 ios xrvs and 2 junos vmxs) but it works.

Theres a couple things i eventually found out particularly with the ios xrv.

First to make it work in esxi you need serial dupport which is only available in the top tier esxi licence.

Secondly ensure you have sufficient memory and resources.

I would suggest once the virtual boxes are configured id set up ssh and tunnel your way into the virtual boxes via that instead. Less headaches that way.

Also another thing to remember the network cards listed in the virtual machine stats wont reflect whats actually there.

For ios xrv the first network card is the management port (but we dont use that one) so the ports start from nic2 on in esxi.

Vmx needs to use the first two interfaces the rest are counted 0 to what ever.

Ill write up another blog detailing the configuration and some tips about both the ciscos and the juniper boxes.
