QFX5k question

Sat Mar 23 21:00:54 UTC 2019

I have Virtual chassis QFX5100’s running as a switching/routing core with about 80k routes (bgp in routing-instances) and no issues. MX’s are on the upstream borders and downstream BNG’s. The only issue I has was I had some MPLS psuedowire switching on them and found a few glitches.

I have 4 QFX51xx switches in a virtual chassis and have no problems pushing that much traffic through them for several hundred servers with 10GB uplinks.

Hey there, 

I am trying to get my hands on some QFX5000s and I have a rather quick question.

In the past, I often used MX + EX where MX did routing and I connected all uplinks/peering and EX, and EX did switching, i connected my servers to ex.

in QFX, I am trying to see if I need EX or not? more importantly (besides from what juniper papers say) are there any known issues people run into for a small scale deployment. (100mbps-1gbps range 1 rack, 20 servers) 

my plan is to have QFX to it all, but i am worried, if this is too much for QFX, if you have relative experience on this , feel free to let me know

thanks in advance
