This paper discusses the P2MP in band OAM framework primarily related to OAM and related management in MPLS-TP networks. Current MPLS-TP P2MP is when no return path exists or not used and the other is when an "out-ofband" return path exists and used. The P2MP network MPLS-TP data transfer scheme from the root node to the leaf nodes of the In-band OAM because it supports, MPLS-TP OAM 50ms time, one of the requirements in the OAM packet can be processed. MPLS-TP Network P2MP data transfer scheme Leaf Node add / delete Return Path Bandwidth setting technology.
