Create VS R80.10 on VSX running R80.20. Is it possible?

Hello,

I need to test  sk164472  and is necessary to run R80.10 or older. I have a cluster VSX with R80.20 and I don´t know if is possible to create a VS with a prior release than the version running on VSX.

Any help or guidance is welcome.

Thank in advance.

To answer your immediate question, no, there is not a way for VSs to be on different software versions. There is nothing at all virtual about VSX beyond the virtualization involved in preemptive multitasking. It's just multiple routing tables and firewall policies on a single OS. If you are familiar with rdomains, VRFs, or network namespaces, that's what VSX is.

There is less separation between VSs on the same box than there is between FreeBSD jails or Solaris/illumos zones.

Did you review sk112454 for R80.20 and above, did it not suit your situation?

Virtual Systems within a VSX gateway are the same version.

I guess so if the functionality is equivalent in both versions...

Thank you Chris_Atkinson

Ok. I was thinking on container technology rather than VRFs...

Thank you so much  Bob_Zimmerman

Come to think of it, I don't think even jails or zones would let you run different firewall versions on the same box. Too much of the firewall is actually in the network kernel, which is shared between them. Zones might sort-of work with something like the "brand" feature, but it would be a huge amount of effort (on par with what went into the LX brand). Usermode Linux could let you run multiple kernels with different versions of the firewall extensions, but would get weird in other ways.
