How do I limit NIC usage for multicast in NDDS 3.1a?

Note: Applies to NDDS 3.x

For machines with multiple NICs, it is sometimes useful to specify which NIC(s) to communicate over. Multicast packets will be sent through all interfaces that satisfy the following criteria:

  • It is enabled for multicast 
  • NDDS is configured to use it 

Enabling a NIC for multicast is done outside of NDDS, at the operating system level.

To configure NDDS to not use a particular NIC for multicast traffic, you can disable the use of that NIC (for unicast and multicast), using the domain property nicProperties.

See example attached.
