[j-nsp] Question about Routing Engine Redundancy on MX

[Paul Stewart]

Thanks RAS.. that's interesting as we've never actually tried that...

Have you tried this in a production environment or would you?  Do we have
any idea on whether or not JTAC would support this configuration officially?

I realize these are loaded questions - just really curious on this topic as
it opens up some "new possibilities" for us in some deployments...  Our SE
basically told us to "run" from this idea previously...

Cheers ;)

Paul

As long as they're reasonably similar it should work fine. For MX that
pretty much means RE-2000 and RE-1300, you have no hope in hell of
mismatching the new ones (RE-1800x2/4, which require 64-bit JUNOS) with the
old ones. For some definition of work of course (for all of the active
redundancy), where in my experience the answer is "it doesn't".
