Objective
How to configure "Provider-Bridge" (Q-in-Q) on a S-Series
Environment
  • S-Series
  • K-Series
  • 7100
  • Q-in-Q
Procedure
When the bridge mode is set to provider-bridge, switches in a service provider network relay packets based on service VLANs (using S-TAGs) rather than customer VLANs (using C-TAGs). The VLAN configuration now operates over the S-VLAN for relay operations instead of the C-VLAN. Customer-provided STP and MVRP addresses are preserved in the packets, but are ignored in the provider network. The provider network can be configured to use its own Spanning Tree and MVRP addresses to switch packets around the S-VLAN.

Any customer traffic received on a provider network ingress port will be placed in the S-VLAN defined for that port, and will be delivered to the customer network connected to the provider network egress port. For bidirectional VLAN traffic between the two remote customer networks, both of these provider ports must be configured on the same service VLAN

 
Provider Edge Switch 1:
set bridge mode provider-bridge
set vlan create 400
set port vlan ge.1.1-2 400 modify-egress
set vlan egress 400 ge.1.1 untagged
set vlan egress 400 ge.1.2 tagged
set vlan create 500
set port vlan ge.1.2-3 500 modify-egress
set vlan egress 500 ge.1.3 untagged
set vlan egress 500 ge.1.2 tagged

Provider Edge Switch 2:
set bridge mode provider-bridge
set vlan create 400
set port vlan ge.2.2-3 400 modify-egress
set vlan egress 400 ge.2.1 untagged
set vlan egress 400 ge.2.2 tagged
set vlan create 500
set port vlan ge.2.2-3 500 modify-egress
set vlan egress 500 ge.2.3 untagged
set vlan egress 500 ge.2.2 tagged
Please see the link to the manual below for a complete explanation of the above sample configuration, along with diagram

Additional notes
The default mode for bridging and routing of external (customer) VLANs through an Extreme Networks S- K- and 7100-Series switch is called Customer Bridging. In a customer bridge, all packets are bridged and routed based on the VLAN identified in the C-TAG. Routing through and egress from the network must be configured on a per-VLAN basis, so there must be a VLAN configured for each VLAN passing through the switch.

For more information, see the below manual:
