QinQ vlan bridging

Fri Nov 05, 2021 5:41 pm

Hello,

We recieve VLAN 1373 tagged form our service provider.
This VLAN is QinQ compatible.

The situatie is:
service provider <sfpplus12> router4 <sfpplus5> router2

I want to bridge VLAN 1373 (outer vlan) from router4 to router2
And from router2 i wan't to add the inner vlan's.

But i cannot get it working, also i cannot find a lot of documentatie about QinQ.
Can i even do it with a router?

the easy way would be do vlan-filtering on those routers.
Then you can use tunneling method by ticking "use service tag"

Oke, so adding a bridge with VLAN Filtering on.

and then? do i need to add the outer vlan 1373 as a port to the bridge on both ports?

And setting the service tag on vlan 1373 (on each port? so port to service provider and the port to router2)?

I got it working, but without the option service-tag=yes.
