Configuring Point-to-Multipoint Connections
In point-to-multipoint (P2MP) connections, one master connection endpoint, or root, can be configured
to connect to multiple slave endpoints, or parties.
P2MP SPVCs and SPVPs are created between a root endpoint and multiple ATM CPEs. During P2MP
connection setup and rerouting, the root is responsible for routing and rerouting, and the parties are
responsible for responding to requests from the master. The root and its parties are configured on the
switch to which the ATM CPE connects. These endpoints can be on the same switch or on different
switches.
P2MP functionality is necessary for the following applications:
•
•
The procedures in this section describe how to configure P2MP connections on a PXM1E. For more
detailed information on planning and establishing P2MP connections in a PNNI network, refer to the
Cisco PNNI Network Planning Guide for MGX and SES Products.
Keep the following in mind when configuring P2MP connections on Cisco MGX 8850 (PXM1E) and

CBSMs cannot originate or terminate P2MP connections.
ABR P2MP connections are not supported.
P2MP connections support uni-directional traffic in the root-to-leaf direction only. Leaf-to-root
traffic is not supported.
Unicast (P2P) traffic has a higher priority than multi-cast (P2MP) traffic. P2MP connections have a
default routing priority of 8.
P2MP connections do support CUGs.
For a P2MP connection, the root can be on any port that supports slot multicasting. The port that is
the root of the connection does not need to support port multicasting. A port on which multiple
parties are assigned must support port multicasting. For example, if you add a second party on a port
that does not support port multicasting, the connection will not route.
