What does "RTINetioSender_addDestination:no transport for request" mean?

Note: Applies to RTI Connext 4.x and above

The message RTINetioSender_addDestination:no transport for request is a warning that RTI Connext could not find a transport for a specified peer locator. 

The UDPv4 and shared memory transports are installed by default. When a node tries to add a destination route to its internal database, it verifies that the transport is installed. You will see this warning if:

  • The transport is not installed.
  • The peer locator is a multicast address and multicast is not enabled on the transport.
  • Peer applications have different transport configurations, such that when a peer locator is received via discovery, that locator cannot be resolved by any available local transport.
