PBB I-VPLS

Existing SAP processing rules still apply for the I-VPLS case; the SAP encapsulation definition on Ethernet ingress ports defines which VLAN tags are used to determine the service that the packet belongs to:

I-VPLS services do not support the forwarding of PBB encapsulated frames received on SAPs or Spoke-SDPs through their associated B-VPLS service. PBB frames are identified based on the configured PBB Ethertype (0x88e7 by default).
