Juniper hardware recommendation

Routers for the whole Alphabet Soup.

     MX204, MX960 are pretty much headache free.  Heck even MX240 could 
be a good start if you are on a budget.
     ( Watch for the EoL )

Distribution ( MPLS Alphabet Soup without VXLAN/EVPN )

     QFX5100 made us feel like being full time members of the Juniper QA 
Team.  But once your find ALL the limitation of their chipset, they 
won't fail you.
     ( Chipset limitations are not always handled by the configuration 
and rendered ports unusable until the device is rebooted ... Or make you 
wonder why the heck it ain't working until you find some notes in an 
obscure PR )

     We're going up to 100Gbps (and then 200Gbps) in distribution and 
we're feeling good about the QFX being able to handle it.

     PS: EVPN worked well in the Lab, but we're no using in our "scheme".
