◆
The inner VLAN tag of a customer packet entering the edge router of a
service provider’s network is mapped to an outer tag indicating the
service provider VLAN that will carry this traffic across the 802.1Q
tunnel. This process is performed in a transparent manner as described
under
"IEEE 802.1Q Tunneling" on page 243
.
◆
When priority bits are found in the inner tag, these are also copied to
the outer tag. This allows the service provider to differentiate service
based on the indicated priority and appropriate methods of queue
management at intermediate nodes across the tunnel.
◆
Rather than relying on standard service paths and priority queuing,
QinQ VLAN mapping can be used to further enhance service by defining
a set of differentiated service pathways to follow across the service
provider’s network for traffic arriving from specified inbound customer
VLANs.
◆
Note that all customer interfaces should be configured as access
interfaces (that is, a user-to-network interface) and service provider
interfaces as uplink interfaces (that is, a network-to-network interface).
Use the
uplink
command to set an
interface to access or uplink mode.
◆
When the
remove-ctag
option is specified, the inner-tag containing
the customer’s VID is removed, and the outer-tag containing the
service provider’s VID remains in place.
