EX4300 Q-in-Q + common trunk (ELS) to ??

Hello everyone!


I've been struggling with ESL on the 4300 trying to mix a normal vlan trunk with QinQ configuration.

I need to configure a normal trunk between two EX4300 but, one of those vlans in the trunk, needs to be a C-Vlan in the QinQ uplink later.

I really don't know how to configure this. I’ve tried making a mix using Ethernet-switching and qinq syntax, but unfortunately didn’t work.

I leave you the config that I used for QinQ and topology, hoping that the topology is more clear to explain you what I need.

I believe you are trying to run both Q-in-Q and standard 802.1q/tagged on same interface/AE.  I do not think this is supported.  I think interface must be one of either Q-in-Q or standard 802.1q tagged.


Maybe someone else smarter than me can provide a better answer.  Have you opened TAC case and ask them?


Good Luck

Hi RCC, thanx for your answer.


I couldn't figure out yet how to make a simple vlan trunk in order to be able to extract one vlan (or in this case, ae unit) and add it to the service vlan syntax.



set vlans Vlan1191_S-Vlan interface ae0.1191   ---> S-Vlan
set vlans Vlan1191_S-Vlan interface ge-0/0/0.550 ---> C1-vlan
set vlans Vlan1191_S-Vlan interface ge-0/0/1.544 ---> C2-vlan
set vlans Vlan1191_S-Vlan interface ae1.687 ---> C3-vlan (vlan from the trunk)

set interfaces ae1 unit 687 ???????

I'll try to open a case with the Jtac and wait for their knowledge
