9.3.4 Typical Applications of the Dot1q-tunnel

Scenario
ISP internet edge switch PE1 and PE2 forward the VLAN200~300 data between CE1
and CE2 of the client network with VLAN3. The port1 of PE1 is connected to CE1,
port10 is connected to public network, the TPID of the connected equipment is 9100; port1
of PE2 is connected to CE2, port10 is connected to public network
