Hey man Zilal,
As you may be knowing that there are routing protocols which use multicast as a means of giving out information you can easily setup tht and use DEBUG commands for respective routing protocols and SEE for yourself the magic of multicast happening. 
eg. EIGRP uses 224.0.0.10
RIP V2 uses 224.0.0.9
OSPF uses 224.0.0.5--- AllSPFARouters
224.0.0.6----AllDRRouters
etc.
If you have a network protocol analyzer you can easily VIEW the interaction too.
Let me know if you face any problems man.
Good Day.
