Epipes with PBB are supported only on 7210 SAS-T operating in the network mode.
A PBB tunnel may be linked to an Epipe to a B-VPLS. MAC switching and learning is not required for the point-to-point service (all packets ingressing the SAP are PBB encapsulated and forwarded to the PBB tunnel to the backbone destination MAC address, and all the packets ingressing the B-VPLS destined for the ISID are PBB de-encapsulated and forwarded to the Epipe SAP).
A fully specified backbone destination address must be provisioned for each PBB Epipe instance to be used for each incoming frame on the related I-SAP. If the backbone destination address is not found in the B-VPLS FDB, packets may be flooded through the B-VPLSs
All B-VPLS constructs may be used, including B-VPLS resiliency and OAM. Not all generic Epipe commands are applicable when using a PBB tunnel.
