Multi network configuration using SBN

[jcqhagg]

Hi,
I am doing some tests with cFS and I'm trying to create a network with three different cFS applications and two different SBNs. Basically I'm trying to have the same configuration shown in the Context Diagram slides in the doc folder. The only difference is that I don't have the "ProcessorID 2".

The SBN configuration file I use is this:

#include "sbn_tbl.h"
#include "cfe_tbl_filedef.h"
  
SBN_ConfTbl_t SBN_ConfTbl =
{
    .ProtocolModules =
    {
        {
            .Name        = "UDP",
            .LibFileName = "/cf/sbn_udp.so",
            .LibSymbol   = "SBN_UDP_Ops",
            .BaseEID     = 0x0100
        },
    },
    .ProtocolCnt    = 1,
    .FilterCnt      = 0,
    .PeerCnt        = 4,
        .Peers =
        {
            {
                .ProcessorID  = 4, //application 1, network 0
                .SpacecraftID = 0x42,
                .NetNum       = 0,
                .ProtocolName = "UDP",
                .Address      = "127.0.0.1:2237", //Format - IP:PORT
                .TaskFlags    = SBN_TASK_POLL
            },
            {
                .ProcessorID  = 4, //application 1, network 1
                .SpacecraftID = 0x42,
                .NetNum       = 1,
                .ProtocolName = "UDP",
                .Address      = "127.0.0.1:2238", //Format - IP:PORT
                .TaskFlags    = SBN_TASK_POLL
            },
            {
                .ProcessorID  = 2, //application 2, network 0
                .SpacecraftID = 0x42,
                .NetNum       = 0,
                .ProtocolName = "UDP",
                .Address      = "127.0.0.1:2235", //Format - IP:PORT
                .TaskFlags    = SBN_TASK_POLL
            },
            {
                .ProcessorID  = 3, //application 3, network 1
                .SpacecraftID = 0x42,
                .NetNum       = 1,
                .ProtocolName = "UDP",
                .Address      = "127.0.0.1:2236", //Format - IP:PORT
                .TaskFlags    = SBN_TASK_POLL
            },
        },
};
  
CFE_TBL_FILEDEF(SBN_ConfTbl, SBN.SBN_ConfTbl, SBN Configuration Table, sbn_conf_tbl.tbl)

When application 3 runs, SBN gives the following message and exits:

EVS Port1 66/3/SBN 5: initializing net: 0
EVS Port1 66/3/SBN 5: network #0 not configured
EVS Port1 66/3/SBN 2: ERROR: could not initialize SBN: unable to initialize interfaces
EVS Port1 66/3/CFE_SB 46: Pipe Delete Error:Bad Argument,PipedId 0,Requestor SBN
EVS Port1 66/3/SBN 2: failed to delete subscription pipe (Status=-905969661)
EVS Port1 66/3/SBN 5: unable to tear down sub pipe
EVS Port1 66/3/SBN 2: ERROR: could not clean up SBN
1980-012-14:02:43.64941 CFE_ES_ExitApp: Application SBN called CFE_ES_ExitApp
EVS Port1 66/3/CFE_ES 14: Exit Application SBN Completed.
EVS Port1 66/3/CFE_TIME 21: Stop FLYWHEEL

Which configuration should I use to make this network functional? Is there an example showing how to do this?

I'm running this in a Linux machine (x86_64), one process for each application.
CFE version: v6.8.0-rc1+dev1030
SBN version: 1.18.0 (protocol version 6)
cFS version: Aquila

Thank you!
