5.4.4 Typical application of VLAN-translation
Scenario
Edge switch PE1 and PE2 of the ISP internet support the VLAN20 data task
between CE1 and CE2 of the client network with VLAN3. The port1 of PE1 is connected
to CE1, port10 is connected to public network; port1 of PE2 is connected to CE2, port10
is connected to public network. (as shown in Figure5-4)
