- VxWorks is causing problems by forwarding broadcast messages.
-
- Here's the deal : I have a development system that is broadcasting over
- FDDI to a specific IP address. The IP address is a Unix box, and the
- FDDI MAC address is a broadcast. I'm using the AP Labs driver.
-
- On my analyzer I see the broadcast message being retransmitted by the VxWorks
- based cage. The messages are UDP/IP, so the Unix machine sees both the
- broadcast, and the retransmitted message.
-
- It appears to me that VxWorks is doing IP forwarding of broadcast messages.
- This is a definate no no.
-
- Does anyone have any experience with this?
-
- Does anyone know how to turn this behavior off?
-
- Thanks BillB.
