Correction - QFX5110 can now route VLAN/IP to VNI via this configuration:
https://www.juniper.net/documentation/en_US/junos/topics/concept/evpn-vxlan-qfx5110-l2-vxlan-l3-logical.html
I was no aware this information had been put out there. Min SW would be
17.3R3, but 18.1R3-S[latest, now 4] would be recommended.
Please also note this functionality is not yet 100% supported as a Border Leaf
for EVPN/VXLAN, so full "support" may not be yet available, despite the
documentation. I think this may be major reason this support has not yet been
announced. At least as far as I know, outside of this one link, I believe this
is not announced or documented anywhere else.
Today I am using only 10K or MX as Border Leaf.

I do believe that QFX5110 is not really "certified" as a EVPN/VXLAN Spine.
Your design is what Juniper refers to as CRB - Centralized Route/Bridged. That
is, VXLAN L3 at the core, versus the edge. The core is generally an IP Fabric.
Do matter what, you would need either MX or QFX10K model to talk to outside
IP world, at least today. You could talk server to server with your DC, but
not outside, which I assume is not what you want.

OK. So, the main question is whatever you are expecting to route between
VXLAN (or between a VXLAN and a VLAN). EX4600 is only able to do L2
stuff with VXLAN. 5110 is able to route between VXLAN and may be able
under some conditions to route between a VLAN and a VXLAN.
