Configuring IEEE 802.1Q Tunneling
IEEE 802.1Q tunneling (QinQ tunneling) uses a single Service Provider VLAN
(SPVLAN) for customers who have multiple VLANs. Customer VLAN IDs are
preserved and traffic from different customers is segregated within the service
provider’s network even when they use the same customer-specific VLAN IDs. QinQ
tunneling expands VLAN space by using a VLAN-in-VLAN hierarchy, preserving the
customer’s original tagged packets, and adding SPVLAN tags to each frame (also
called double tagging).
This section describes commands used to configure QinQ tunneling.
General Configuration Guidelines for QinQ
1.
Configure the switch to QinQ mode ( dot1q-tunnel system-tunnel-control ).
2.
Create a SPVLAN ( vlan ).
3.
Configure the QinQ tunnel access port to dot1Q-tunnel access mode
(
switchport dot1q-tunnel mode ).
