# To enable interoperability with the third-party devices in the public network, set the TPID of the
service provider network VLAN tags to 0x8200. Therefore, the port tags the received frames with the
outer VLAN tag whose TPID is 0x8200.

3) Configuration on devices on the public network
As third-party devices are deployed between Provider A and Provider B, what we discuss here is only
the basic configuration that should be made on the devices. Configure that device connecting with
GigabitEthernet 2/0/3 of Provider A and the device connecting with GigabitEthernet 2/0/1 of Provider B
so that their corresponding ports send tagged frames of VLAN 1000, VLAN 2000 and VLAN 3000. The
configuration steps are omitted here.
