Agree 100%. If you need L3 for 1GE edge, no solution today. That solution
(late 1H2019 or 2H2019) will come with EVPN/VXLAN support on EX4300-MP, from
what I hear. If you can get away with just L2 at 1GE edge, than ESI-LAG to any
L2 Access will work. Yes you can also use QFX5K Agg running
To run EVPN on QFX5100 yes you need extra license – PFL (the less expensive
option). NOTE: PFL and AFL always confusing to me, as which is more!!
You could then run the EX4300 connections as an ESI-LAG, versus MC-LAG – has
advantages of standards based, can scale horizontally in the core, and
Hey Richard,
I think there are two separate issues here. Lot of people looking at
Fusion aren't choosing it for technology, they are choosing it for
media, as 1GE L3 ports are not available. So options are
a) L2 aggregation
b) Fusion
c) Wait for JNPR to release some MX244 with 4xQSFP28 + 40xSFP+
We are looking at a mix of QFX5100-48S and EX4300-32F (somewhere between 6
and 10 devices total). It looks like the QFX supports EVPN, but Juniper
doesn't seem to have any relatively inexpensive 1Gbe devices with EVPN
support.
We are planning on dual-homing most of our buildings (strictly L2,
I might suggest you look at an EVPN based design instead. This is going to be
Juniper's #1 go to in the future. I believe things like Junos Fusion and
MC-LAG, etc. may still be supported, but secondary to EVPN and associated
features.
What is your planned SD devices? QFX5???
