Just FYI, but Q-in-Q is not really going to help. What he might be able to do is create a standard Q-Tag/Trunk between the switches (Q-in-Q not required). Then create a L2 Cobranet VLAN than spans...

For EX3300 I would suggest you run SW image of either 12.3R12 or 15.1R5 - latest version of either, and not use 14.1x53-D40 for this product or anyother legacy (older non-ELS) EX switches. Just my 2...

Hi rccpgm, I'm use junos version 14.1x53-D40 due to advise from so called "Juiper PS" as per LLD that created by them. Is it junos ver 15.1R5 have more issue now when i read in this forum. Thanks
View ArticleRe: EX3300 normal port suddenly change to VC-Port?
In that case I would recommend going to 12.3R12 (latest) and wait for next releases of 15.1. I would not suggest running 14.1 on any legacy EX switch. This is just my [fairly qualified] view. I am...

rccpgm, Yes, QinQ or l2circuits would work in this situation. The issue was that the existing infrastructure is setup Layer 3 between the buildings. Thus they were not in a position to do the...

It may work, but that level of aditional complexity is not needed at all for what he needs to do. It is basically using a sedgehammer to pound a nail. VPLS etc. is not a feature offered, nor would...

I would guess that this function hasn't been implemented on DHCPD on QFX. You need to use JDHCPD instead which is the way to go moving forward. Here is a configuration example for JDHCPD-style...
