Configuring Point-to-Multipoint SoftPVC Con nections
To configure point-to-multipoint circuit emulation services (CES) soft PVC connections see the
“Configuring Point-to-Multipoint CES Soft PVC Connections” section on page 19-63 .
Figure 7-11 illustrates the point-to-multipoint softPVC connections used in the following examples.

Guidelines for Creating Point-to-Multipoint Soft PVCs
Perform the following steps when you configure point-to-multipoint soft PVCs:
Step1 Determine which ports you want to define as participants in the point-to-multipoint softPVC.
Step2 Decide which of these ports you want to designate as the leaves of the soft PVC connection and which
of these ports is the root. The leaves of the connection would be the Soft PVC destinations and the root
would be the source.
Step3 Retrieve the ATM addresses of the destination end of the softPV C using the show atm address
command.
Step4 Retrieve the VPI/VCI values for the circuit using the show atm vc command.
Step5 Configure the source (active) end of the softPVC. At the same time, complete the point-to-multipoint
soft PVC setup using the information derived from Step 3 and Step 4. Be sure to select an unused
VPI/VCI value (one that does not appear in the show atm vc display).
Point-to-multipoint soft PVC connections have the following restrictions:
Point-to-multipoint soft PVC connections can be sourced-from or term inated-on ATM and IMA
interfaces only.
Dynamic modification of the CTTR (connection traffic table row) on point-to-multipoint soft PVCs
is not allowed.
