The configuration details for the Edge 2 switch mirrors the configuration for the Edge 1 switch. All customer traffic received on port A1 from customer A's site 2 will be associated with S-VLAN 100. Similarly, all customer B's site 2 traffic will be associated with S-VLAN 200.
To configure the switch, follow these steps:
Procedure
-
Enable QinQ:
Edge 2(config)# qinq svlan tag-type 88a8
-
Reboot the box with the configuration saved to transfer into S-VLAN bridge mode.
-
Configure S-VLANs and customer ports connected to the customer network.
Edge2(config)# svlan 100
Edge2(svlan-100)# untagged A1
Edge2(svlan-100)# exit
Edge2(config)# int A1 qinq port-type customer-network
Edge2(config)# svlan 200
Edge2(svlan-200)# untagged A2
Edge2(svlan-200)# exit
Edge2(config)# int A2 qinq port-type customer-network
-
Configure the provider ports leading to the core of the provider network.
Edge1(config)# svlan 100 tagged A3, A4
