EX4300 Q-in-Q + common trunk (ELS)...how 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.

Regards!

EX4300
