Multicast

Hi.
I’m hoping someone will be able to give me a bit of advice.
In code I’m trying to set up a QoS policy that sets specific topic names to be transported on particular multicast groups. For example, Topic1 is transported on 239.255.100.101 and topic2 on 239.255.100.102.
I’d like to be able to define common code that generates a policy that includes the multicast group to topic names for a number of topics to allow us to do a bit of code reuse.
From doing a bit of reading online it looks like it can be done but I’m just not entirely sure how.

I'm sending images using a docker. I created a publisher and subscriber which sends a simple image. And I want to use the recording service to log info from this images. 

I created this xml, based on the example in the RTI_RecordingService_UsersManual.pdf page 27.

Hello all,

First, in here (https://community.rti.com/comment/reply/2592) you need to add that you have to allow unknow peers for udp loopback.

You have also a duplicate, worse article which you should merge with the above one and delete: https://community.rti.com/kb/how-do-i-configure-rti-data-distribution-service-not-use-multicast

I have four hosts called A, B, C, D.

A has IP Address 192.168.0.97.
B has IP Address 192.168.0.99.
C has IP Address 192.168.0.98.
D has IP Address 192.168.0.99.

A and B are connected to each other through an ethernet switch S1.
C and D are connected to each other through an ethernet switch S2.
S1 and S2 are not connected to one another.

Hi,

We need DDS to be picked up over multiple subnets. I know that the default Multicast TTL setting is 1, which won't alllow this. I found the article here:

Hello RTI Community,

I'm having trouble getting multicast communications working between a connext micro and connext pro application.
