In the Schedule Live Network Collection task in the Task Manager, check the Multicast Path box as shown in the following figure. This ensures that the multicast routing table is collected. The multicast tree and subsequent display is constructed via the olist and ilist that is contained in the collected multicast routing table.

The collected data is stored in directory /u/wandl/data/collection/.LiveNetwork/multicast_path/. The following is an example for IOS of the multicast routing table that is collected.
