Hi Mahesh,
Not quite - the (Source,Group) specifies the Source of the Multicast stream and the IP address of the group. So if the Multicast Source was a server with an IP address of 192.168.1.20 and it was sending to Multicast group 239.5.5.55 then the entry would read:
(192.168.1.20,239.5.5.55)
The (*,G) entry indicates a shared tree multicast tree - all of the sources for the group are using the same RP.
My multicast is not that strong, so I can't explaion in any great detail!
There is an expanation on the difference between source and shared trees here, which may prove useful:

Many thanks
