QinQ setup Assistance/Verification

Mon May 08, 2023 11:31 pm

I am working on a QinQ config for an end user, I want to make sure this looks correct before I reach out and have them retest.

See drawing for how we are looking for the VLANs to work

We are receiving QinQ from the customer on the A end, this is being tagged by them with a S-VLAN and C-VLAN.
This is going into router 1, where I am trunking it along to router 2.
Router 2 is then going to strip the S-VLAN off and leave only the C-VLAN to hand-off to the end user on the Z end.
Likewise it needs to add that S-VLAN back to traffic it is receiving from the end user at the Z end.

Both routers are RB3011's

 -----Router 1 config-----
 
 /interface bridge
add ether-type=0x9100 name=bridge1 vlan-filtering=yes
/interface vlan
add interface=bridge1 name=vlan100 vlan-id=100
/interface bridge port
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=ether2
/interface bridge vlan
add bridge=bridge1 tagged=ether1,ether2 vlan-ids=100



-----Router 2 config-----
/interface bridge
add ether-type=0x9100 name=bridge1 vlan-filtering=yes
/interface vlan
add interface=bridge1 name=vlan100 vlan-id=100
/interface bridge port
add bridge=bridge1 hw=no interface=ether1
add bridge=bridge1 hw=no interface=ether2 pvid=100 tag-stacking=yes
/interface bridge vlan
add bridge=bridge1 tagged=ether1 untagged=ether2 vlan-ids=100
