Configuring Two-to-Two VLAN Mapping

In two-to-two VLAN mapping, the outer VLAN and the inner VLAN carried in a double-tagged uplink
frame received at the downlink port on the edge device of an SP network are called the original SVLAN
and CVLAN, and the VLANs that the edge device substitutes for the original SVLAN and CVLAN are
called the new SVLAN and CVLAN.
Perform two-to-two VLAN mapping on the edge device that connects two SP networks, on Device C in
Figure 1-2 for example.
Follow these steps to configure a two-to-two VLAN mapping:
Enter system view
Configure an uplink policy for the uplink
port to replace the original CVLAN with
the new CVLAN
Configure an uplink policy for the
downlink port to replace the original
SVLAN with the new SVLAN
Configure a downlink policy for the
downlink port to replace the new
SVLAN and CVLAN with the original
SVLAN and CVLAN
Enter the interface view of the downlink
port
Configure the downlink port as a trunk
