>From your log,  i understand that, OSPF Hello  packets are sent with
Multicast IP 224.0.0.5.   To receive this kind of multicast up to the
stack,  Quagga-daemons like ospf would need to register for that required
Group  using ADD_MEMBERSHIP socket option with the specified group.i hope
this would be present in quagga.

Issue could be with Multicast  DATA receiption on Sokeris Target.

Cross check the ifconfig  RX packets counters in box2.   As tcpdump sets
the interface into promiscuous  mode, it will certainly show the packets at
L2 Level in promisc mode.  i.e all packets on network.

Check the packets arrived using ifconfig RX counters only. And ensure
that  224.0.0.5 equivalent MAC is  available  in   cat
/proc/net/dev_mcast     file contents under that interface.
