Guidelines for Creating Point-to-Multipoint Soft PVCs

Perform the following steps when you configure point-to-multipoint soft PVCs:
Determine which ports you want to define as participants in the point-to-multipoint soft PVC.
Step 1
Step 2 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.
Retrieve the ATM addresses of the destination end of the soft PVC using the show atm address
Step 3
command.
Retrieve the VPI/VCI values for the circuit using the show atm vc command.
Step 4
Configure the source (active) end of the soft PVC. At the same time, complete the point-to-multipoint
Step 5
soft PVC setup using the information derived from
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 terminated-on ATM and IMA
interfaces only.
Dynamic modification of the CTTR (connection traffic table row) on point-to-multipoint soft PVCs
is not allowed.
