Point-to-Multipoint (E-tree in the MEF classification, hereinafter also referred to as the P2M service) is a transport service involving a single service interface of a CPE device transmitting traffic in a centralized way to multiple interfaces on top of an Ethernet network based on a tree topology.
The hierarchical structure of the P2M service simplifies network management, ensures the reliability of data transfer without duplication, and improves the scalability of the network by accommodating new devices.
When creating a P2M service, you must assign one of the following roles to each service interface:
Frames complying with the IEEE 802.1Q and 802.1AD standards can be transmitted.
