4.5.5
Q-in-Q
Q-in-Q is commonly referred as VLAN stacking in which VLANs are nested by adding
two tags to each frame instead of one. Network service provider and users both can
use VLANs and makes it possible to have more than the 4094 separate VLANs
allowed by 802.1Q.
There are three ways in which a machine can be connected to a network carrying
double-tagged 802.1ad traffic:
via a untagged port, where both inner and outer VLANs are handled by the
switch or switches (so the attached machine sees ordinary Ethernet frames);
via a single-tagged (tunnel) port, where the outer VLAN only is handled by the
switch (so the attached machine sees single-tagged 802.1Q VLAN frames); or
via a double-tagged (trunk) port, where both inner and outer VLANs are handled
by the attached machine (which sees double-tagged 802.1ad VLAN frames).
