P2MP-TE —point to multipoint traffic engineering
P2MP tree —The ordered set of routers and TE links that comprise the paths of P2MP TE sub-LSPs from
the ingress router to all of the egress routers.
P2MP tunnel —A group of one of more P2MP LSPs. A tunnel has the following 3-tuple key:
•
P2MP ID
•
Tunnel ID
•
Extended tunnel ID.
PIM —Protocol Independent Multicast
PIM-SM —PIM Sparse Mode, see RFC 4601
PIM-SSM —PIM Source Specific Multicast, a subset of PIM-SM. See RFC 4601.
Pruning —The process of removing a sub-LSP from a a P2MP LSP.
Receiver —A recipient of traffic carried on a P2MP service supported by a P2MP sub-LSP. A receiver is not
necessarily an egress router of the P2MP LSP. Zero, one, or more receivers may receive data through a given
egress router.
Remerge —A condition that occurs at an intersecting node when two data streams belonging to the same
P2MP LSP merge into onto one data stream as they exit the intersecting node.
Sibling LSP —Two LSPs that belong to the same P2MP tunnel, meaning that the session objects are the same
for both LSPs.
Sibling sub-LSP —Two sub-LSPs that belong to the same P2MP LSP, meaning that the session and sender
template objects are the same for both sub-LSPs.
Source —The sender of traffic that is carried on a P2MP service supported by a P2MP LSP. The sender is
not necessarily the ingress router of the P2MP LSP.
Tailend router —An egress PE router that is at the “tailend” of a P2MP tunnel.
