Hi guys,
Thank you for the answers. It's really sad to hear about it and there're
two equally unsatisfactory solutions: vlan mapping or vlan ranges
reservation..
Thanks again for the explanation!

Unfortunately, Allan is correct... don't expect use QinQ in ELS system, will be
very annoying trying to find a way the let the packets flow inside. And they
don't flow gracefully....
A friend told to me: QFX are Ferraris.... I answer him: then Juniper, don't
knows how to drive.

Hello,
I have a mixed VC (QFX5100 and 3500, if it means) with 14.1X53-D40.8.
There's an interface that incapsulates C-VLANs into S-VLAN:
set interfaces ae31 flexible-vlan-tagging
set interfaces ae31 mtu 9216
set interfaces ae31 encapsulation extended-vlan-bridge
set interfaces ae31 unit 3174 vlan-id-list 21-22
set interfaces ae31 unit 3174 input-vlan-map push
set interfaces ae31 unit 3174 input-vlan-map vlan-id 3174
set interfaces ae31 unit 3174 output-vlan-map pop
The other side:
set interfaces ae0 flexible-vlan-tagging
set interfaces ae0 mtu 9216
set interfaces ae0 encapsulation extended-vlan-bridge
set interfaces ae0 unit 3174 vlan-id 3174
S-VLAN configured like this:
set vlans sv3174-qinq interface ae0.3174
set vlans sv3174-qinq interface ae31.3174
At this point everything works fine, but if I create a VLAN with the
same ID as a C-VLAN (21 or 22):
set vlans v21-user vlan-id 21
the traffic in the C-VLAN 21 stops.
When I delete v21-user the traffic in C-VLAN 21 restores.
What's wrong with it and how can I fix it?
Hi,
QinQ on the QFX and all the other boxes running the ELS style is a bit
of an abomination.
VLANs configured with extended-vlan-bridge interfaces are forwarded
using a different daemon than VLANs forwarded using the
classic ethernet-switching daemon.
It's quite likely that you cannot share VLAN IDs between the two methods of
forwarding.
I would bug Juniper about this, but I wouldn't expect them to be able to
fix it.
Best regards,
Allan Eising
