z Third-party devices are deployed between Provider A and Provider B, with a TPID
value of 0x8200.
The expected result of the configuration is as follows:
z VLAN 10 of Customer A and Customer B can intercommunicate across VLAN
1000 on the public network.
z VLAN 20 of Customer A and Customer C can intercommunicate across VLAN
2000 on the public network.
z Frames of the VLANs other than VLAN 20 of Customer A can be forwarded to
Customer D across VLAN 3000 on the public network.
