ros2multicast
The package provides the multicast command for the ROS 2 command line tools.
The tool can be used to check if multicast UDP packets are passed between two endpoints.
First invoke the following command on one machine:
$ ros2 multicast receive
While the first machine is waiting for a packet to arrive invoke the following command on another machine:
$ ros2 multicast send
When successful the first machine will output the received message “Hello World!”.
