[j-nsp] JunOS 10.4R8.5 on MX5? Am I forced to run 11.4+?

[Paul Stewart]

Yeah, we just ran into this weird release issue with hardware not being supported - in this case MX10-T .... 

Anyways, I did do a no validate on a downgrade and it was miserable (had to reinstall OS via USB key).  Live and learn ... ;)

Running 11.2R5.4 on a pair of them at moment - as long as you're not doing BRAS functions it seems to work ok with BGP/MPLS/OSPF/IPv6

11.2R4.3 worked with our MX5/MX40s, although we upgraded to 11.2R6.3 because of a mib2d memory leak in 11.2R4.3. Other than that, it worked pretty OK at least with trivial config.
