VM instance is not pinging in Redhat osp 10 [closed]
Hi,
I deployed a redhat osp 10. I have two networks in my overcloud. One in private network (192.168.xx.xx) and other in public (15.xx.xx.xx) for external connectivity. Here are my networks.

I added ICMP allow in rules.
When I provision a VM with private network, it is not pinging. But when I provision a VM with public network. It is pinging.
i understand VMs take the br-int interface for private connectivity and br-ex for external connectivity (Please correct me if i am wrong)
For external connectivity i added the physical interface eno49 for br-ex bridge using ovs-vsctl add-port br-ex eno49 after which VM with 15.xx.xx.xx started pinging.
I followed the same for the private network by adding ens1f1 (private network is connected to this interface) ovs-vsctl add-port br-int ens1f1.
My overcloud nodes use the interface ens1f0 for their communication.
I would like to know which interface br-int takes for private network connectivity.
Is there anything else that needs to be done to get this working?
Regards Krishna
