I presume ip-multicast here and no routing daemon for multicast (like pimd etc.)

Check that you have multicast enabled.
ip a sh | grep -i multicast

Add multicast to your routing table.
ip r a 224.0.0.0/4 dev  <yournetwrokinterface> scope link

like this for eth0
ip r a 224.0.0.0/4 dev eth0 scope link

or the old way
route add -net 224.0.0.0 netmask 240.0.0.0 dev <yournetwrokinterface>

check it:
ip route sh

ping 224.0.0.1

You should get some answers from multicast enabled units on your network. Possibly a few DUP also.

If no answer your problem is in between. Ie local firewall, external firewall, switch with broken broadcaststorm prevention, router etc.

Thank you very much, but does router should support multicast?
