Unable to enable multicastLoop in RFA Java

Options
ron.bove.1
ron.bove.1 LSEG
in RFA

I am trying to configure an RSSL Multicast Consumer transport to run on the same server as the Multicast ADS. In order to do so, I need to enable Multicast Loopback in RFAJ but I don't see any such parameter in the RFA configuration editor or in the Configuration Logging Guide.

    Hi @ron.bove.1

    The RFA APIs do not support this MCAST loopback scenario. Only segmented topologies are supported for the multicast-based connection type. It means the MCAST Provider (ADS or RFA Non-Interactive Provider) and MCAST Consumer must be in a different network only as shown below (it shows as RFA Non-Interactive Provider
    but it also applies to the ADS MCAST as well).

    Hi @ron.bove.1, do you plan to run RFA Java consumer application in the same machine with Multicast ADS machine and connect to ADS using same interface (address/port)?

    Hi @ron.bove.1,

    The ADS server has the "multicastLoop" configuration, did you try it yet?

    @S@N@@SET MULTICAST LOOPBACK@ *"${svc}"."${inst}".RRCP*multicastLoop : FALSE
    #help
        multicastLoop: { True, False }
        Enable/Disable loopback for outbound multicast traffic.
        Default value: FALSE

    Yes, I plan to run the RFA Java Consumer application on the ADS itself. Its for LAB testing. And yes, I have multicast loop enabled on the ADS but I believe it must be enabled on the application as well.
