Hi Steve,
If I understand you right, the config I proposed with loop cable betweem ports 0/0/0 ( egress trunk with my all VLANS) and 0/0/1 (ingress Access with S-Vlan ) and then to use 0/0/2 as egress trunk with Q in Q traffic to SP is valid ? Yes I'll burn more ports with this config I know, but I need to know that it's valid config.
I know that I have to speak with my SP not to strip my external tags.
The other option is to send just normal trunk traffic to my SP and let him do the Q in Q to be transperent for me, but in this link are involeved multiple SPs to my final destination. So this is the reason I want to do the QinQ and I will just want from them to let my QinQ traffic in their network devices.
Regards,
Georgi
