Hi,

   Regarding IPV4 multicast routing, we have tested the platform with 
smcroute (http://www.cschill.de/smcroute/) which is not an OpenSAND tool.

   Attached to this mail, small scripts that gives an example of 
smcroute configuration.
   This configuration set:
- The ST1 as a multicast router and listener for the multicast group 
239.1.1.1
- The GW as a multicast router and listener for the multicast group 
239.1.1.1
- The ST3 as a multicast listener for the multicast group 239.1.1.1

On this files you have to check if interface names and subnetwork 
addresses match your platform.

Trick: regarding the multicast ping, don't forget to use the -t option 
to modify the ttl which is set to 1 by default for multicast addresses.

BR,
Fabrice.
