Using LLIAddStaticEntry to set Static MAC for NDK

Nick,

You may want to try doing this via the NDK's configuration API "CfgAddEntry()".  It should be something like the following:

        bzero(&RT, sizeof(RT));
        RT.IPDestAddr = 0;
        RT.IPDestMask = 0;
        RT.IPGateAddr = inet_addr("195.162.1.50");

        CfgAddEntry(hCfg, CFGTAG_ROUTE, 0, 0,
                sizeof(CI_ROUTE), (UINT8 *)&RT, 0);

You can find out more about the NDK's configuration in the document "spru524_pg.pdf".

Steve,

I want to make sure I'm getting the correct function call setup in doing this.  I'm thinking I will want something more along the lines of:

        bzero(&RT, sizeof(RT));
        RT.IPDestAddr = inet_addr(195.162.1.50); // the desired destination IP address
        RT.IPDestMask = 0xffffffff; // mask to show this is a host route (from host to some destination)
        RT.IPGateAddr = inet_addr(LocalIPAddr); // the DSP's IP address 

Then the same CfgAddEntry() call as you mentioned above. 

However, this doesn't set the MAC address for the given destination. To clarify, I know the IP address and MAC of a destination.  These are static and will not change; therefore I want to add an entry to the NDK's ARP table specifying these values and preempting an actual ARP being sent.  I was looking to the LLIAddStaticEntry() function at first since it sets both the MAC and IP address for a given destination.  I noticed that CFGTAG_CLIENT for CfgAddEntry() has a MacAddr field but I'm not sure I need all the DHCP/DNS support that the programmer's guide mentions.

Does CfgAddEntry() need to be called to add a route before LLIAddStaticEntry() will return without an error?

Nick,

I may have jumped the gun about the call to CfgAddEntry().  You should be able to call LLIAddStaticEntry() how you want.  I think the next step here is to debug the RtCreate() call and determine why it's failing.

Can you put breakpoints in the function RtCreate(), in the file src/stack/route/route.c, at each of the places where it returns 0?  And see which one it's hitting?

Also, there's an example of calling LLIAddStaticEntry() in the code for the NDK's telnet console.  Looking at this may help you to see why this one works, but your is not working.  You can find it in the file src/tools/console/conlli.c at line 150:

            if( !LLIAddStaticEntry( in1.s_addr, mac_address ) )

Nick,

Just wanted to check in on this one.  Were you ever able to try this?

Great news, no problem!
