Configuring two-to-two VLAN mapping
Perform two-to-two VLAN mapping on an edge device that connects two SP networks, for example, on
PE 3 in
Figure 64 . Two-to-two VLAN mapping enables two remote sites in different VLANs to
communicate at Layer 2 across two service provider networks that use different VLAN assignment
schemes.
NOTE:
For the ease of description, the VLAN tags of the double-tagged frames that arrive at the customer-side
port are called foreign CVLANs and SVLANs, and the VLAN tags marked by the edge device are called
local CVLANs and SVLANs.
Perform these tasks to configure two-to-two VLAN mapping:
Task Description
Configuring an uplink policy for the
customer-side port Required
Replace foreign SVLANs with local SVLANs for uplink traffic.
Configuring an uplink policy for the
network-side port Required
Replace foreign CVLANs with local CVLANs for uplink traffic.
Configuring a downlink policy for the
customer-side port
Required
Replace local SVLANs and CVLANs with foreign SVLANs and
CVLANs.
Configuring the customer-side port
Required
Configure VLAN and other settings required for two-to-two VLAN
