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
