At the end of 2022 vMX was announced to be End-of-Life. This was met with dissapointment from my end as it was/is one of the better virtual offerings to emulate a router and be relatively assured that bugs would be at a minimum due to it’s commercial support.

Just recently a new offering from Juniper appeared called vJunOS switch which is more in the vein of vEOS-lab in that it’s free but also requires no login to download (vEOS-lab requires a login to download).

vJunOS Switch is a great addition to my virtual home virtual lab and I’ll demonstrate how to stand it up (doing it my own way and not using the documentation of course!)

I began this lab with the hopes of just showing some simple inter-op use cases but unfortunately so much time lapsed between my last blog post I kept having new ideas before I could publish. So this blog post has these subjects packed in for vMX and vEOS:

• Explore a way to make interface creation less of a burden on KVM:
  • sub-ints (dot1q tagging) as a method to get around KVM interface creation
  • vlans as a method to get around KVM interface creation
• An eBGP unnumbered setup for an underlay using RFC 5549 (interop b/t vEOS and vMX)
• vMX and vEOS EVPN Layer-2 interop (type-2 routes)
• vMX stitch from EVPN to Layer-3 VPN (vpnv4)

Let’s dive in.
