Point to Point Service (P2P)
Point-to-point services are used to provide connectivity between two interfaces of the network
element. When traffic ingresses via one side of the service, it is immediately directed to another
side according to the ingress and egress tunneling rules. This type of service contains exactly two
service points and does not require MAC address-based learning or forwarding. Since the route is
clear, the traffic is tunneled from one side of the service to the other and vice versa.
The following figure illustrates a P2P service.

P2P Service
P2P services provide the building blocks for network services such as E-Line EVC (EPL and EVPL
EVCs) and port-based services (Smart Pipe).
Multipoint Service (MP)
Multipoint services are used to provide connectivity between two or more service points. When
traffic ingresses via one service point, it is directed to one of the service points in the service, other
than the ingress service point, according to ingress and egress tunneling rules, and based on the
learning and forwarding mechanism. If the destination MAC address is not known by the learning
and forwarding mechanism, the arriving frame is flooded to all the other service points in the
service except the ingress service point.
The following figure illustrates a Multipoint service.
