the MAN, the tag is stripped and the original VLAN tag with the customer-related VID is
again available.
This provides a tunneling mechanism to connect remote customer VLANs through a
common MAN space without interfering with the VLAN tags. All tags use EtherType
0x8100 or 0x88A8, where 0x8100 is used for customer tags and 0x88A8 is used for
service provider tags.
In cases where a given service VLAN only has two member ports on the switch, the
learning can be disabled for the particular VLAN and can therefore rely on flooding as
the forwarding mechanism between the two ports. This way, the MAC table
requirements are reduced.
