Not sure how I should title this (C in S Tagging, double tagging, QinQ)?!
I have two switches which I have untagged ports with QinQ enabled on them, those switches take the taffic and each put them in their own VLAN (100 and 200). Those go up to my core and need to get to another location with is across a 3rd party who will take just a single VLAN tag from me. Is there a way within the Juniper EX4550 to take my two VLANS and put them within a new VLAN (300). I could then hand them VLAN 300 they would perserve it and on the other side I would do the reverse and remove the 300 tag to get my 100 and 200 that I can then untag to the correct ports there.
I have done similar with this by taking tagged traffic (VLAN 100) into a access port with another VLAN (300), repeat for other VLAN(s), and that way I have 100&200 inside 300 and can reverse on the other side. I want to do this without burning physical ports!
Thoughts?
Thanks!
