Configuration Procedure
Switch A is a Switch 7750.
■
Enable QinQ on GigabitEthernet2/0/1 port. Set the PVID of the port to 8.
■
Insert the tag of VLAN 10 to packets of VLAN 8 through VLAN 15 as the outer
■
VLAN tag. Insert the tag of VLAN 100 to packets of VLAN 20 through VLAN 25
as the outer VLAN tag.
GigabitEthernet2/0/1 is the upstream port of the outer VLAN tag. It is required
■
that the outer tags of packets of VLAN 10 and VLAN 100 are kept while the
outer tags of packets of other VLANs are removed.
