<p class=MsoNormal>Greetings all,<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>I am using rtems 4.9.2 on a custom PCB with 2 Ethernet
interfaces.  If I don’t add a route my multicast sends fail.  Is this
the correct behavior?<o:p></o:p></p>

<p class=MsoNormal>I am not particularly familiar with multicast.  I have
loopback enabled and when I receive the message it has the IP address of my
interface as <o:p></o:p></p>

<p class=MsoNormal>Opposed to the broadcast address which seems incorrect to me
but is it possibly correct.<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>I tried setting the interface using the IP_MULTICAST_IF but
this does not appear to help.<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>Thanks for any insight,<o:p></o:p></p>
