[SwitchA-GigabitEthernet1/0/3] vlan-vpn enable
# Enable the selective QinQ feature on GigabitEthernet 1/0/3 to tag packets of VLAN 100 through VLAN
108 with the tag of VLAN 1000 as the outer VLAN tag, and tag packets of VLAN 200 through VLAN 230
with the tag of VLAN 1200 as the outer VLAN tag.

[SwitchA-GigabitEthernet1/0/3-vid-1200] raw-vlan-id inbound 200 to 230
After the above configuration, packets of VLAN 100 through VLAN 108 (that is, packets of PC users) are
tagged with the tag of VLAN 1000 as the outer VLAN tag when they are forwarded to the public network
by Switch A; and packets of VLAN 200 through VLAN 230 (that is, packets of IP phone users) are
tagged with the tag of VLAN 1200 as the outer VLAN tag when they are forwarded to the public network.
Configure Switch B.
# Create VLAN 1000, VLAN 1200, VLAN 12 (the default VLAN of GigabitEthernet 1/0/12) and VLAN 13
(the default VLAN of GigabitEthernet 1/0/13) on Switch B.

Configure GigabitEthernet 1/0/13 to remove VLAN tags when forwarding packets of VLAN 13 and
VLAN 1200.

After the above configuration, Switch B can forward packets of VLAN 1000 and VLAN 1200 to the
corresponding servers through GigabitEthernet 1/0/12 and GigabitEthernet 1/0/13 respectively.
