Ignore Specific Ip in discovery network

Hi Howard
Thanks for answering...

I want to disable specific addresses in the Discovery network in DDS, which means for example 192.168.88.* addresses don't discover via rti.
I set this connection interface for another job and I don't want it to be discovered via RTI

In My design :
I have 2 Pcs, I set Network with 10.10.10.1 and 10.10.10.2 for RTI
I set 10.10.10.1 on the one PC and set 10.10.10.2 on the other one. these Ips discovered by RTI and Transfer data together

After that I set another range Ip in connection lan2, 192.168.88.1 and 192.168.88.2, These addresses are reserved for another job and now these ports don't connect to any PCs. When I turn on My Pcs; I found that perhaps RTI retries to discover 192.168.88.* and transferring data in 10.10.10.* have been a lot of delays. when I connect ports of PCs by the Lan wire together, every thing are ok and I don't any delay

At the first I use {"dds.transport.UDPv4.builtin.parent.deny_multicast_interfaces_list", "192.168.100.*"} in policy::Property of DomainParticipantQos , but I didn't get result.

I want to disable or ignore 192.168.88.* address network in discovery cycle rti.

Thanks

Hi
I found the solution it
add "dds.transport.UDPv4.builtin.parent.deny_interfaces_list", "eth3" instead of Ip address in Policy
