    Description

      mcast_sock only bind to a NIC for sending of messages, but not for reception: it actually receives multicast packets on all interfaces (wildcard address 0.0.0.0). Code is UDP.createSockets():

      mcast_sock=new MulticastSocket(mcast_port);

      We should change this to:

      SocketAddress saddr=new InetSocketAddress(bind_addr, mcast_port);
      mcast_sock=new MulticastSocket(saddr);

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
