1, test tools: mint
download link

2, command:
sender:
#mint -s 239.0.0.1 -p 4321 -n 1 -b 100 ; #default, ttl=1. it will cause some issue
FOS will decrement the ttl by one.

receiver:
#mint -r 239.0.0.1 -p 4321 -d 5
Ready to recieve packets:
Received 323 packets..
Notes: need to change the default route to make it make sense.
