VPLS over QinQ Spokes for 7210 SAS-M Configured in Access
Uplink Mode
7210 SAS M devices configured in uplink mode support QinQ spokes or Dot1q spokes, which
allows them to connect to upstream PE nodes which provides IP/MPLS transport.
VPLS is provided over QinQ/Dot1q spokes by:
• Connecting bridging-capable 7210 SAS devices.
• Replicating unknown and broadcast traffic in a service domain.
• Enabling MAC learning over QinQ/Dot1q spokes and access ports (see VPLS MAC
Learning and Packet Forwarding).
• Using a separate forwarding information base (FIB) per VPLS service.
