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 1/0/3 of Provider A and
the device connecting with GigabitEthernet 1/0/1 of Provider B so that their
corresponding ports send tagged frames of VLAN 1000 and VLAN 2000. The
configuration steps are omitted here.
