Example
Network Requirements ■ The selective QinQ feature is enabled on the hybrid port Ethernet3/0/6 which is
connected to the customer network. The outer tag of VLAN 4 is inserted to
packets of VLAN 3 in the customer network, and these tagged packets are
transmitted to the service provider network through Ethernet3/0/15.
■ Configure VLAN 100 as the shared VLAN on the card in slot 3 in order that any
packet returned by the service provider can be unicast to the customer
network.
