Hi there, my problem is that the controller I use need to take information from a mininet host (say, H3) so that it can insert or delete corresponding entry to the p4switch.
According to this post Connect mininet hosts to root namespace, in which it suggests that we can use the actual host as H3. So I followed his step, set H2 to be 10.0.3.3 and root-eth0 on my actual host to be 10.0.3.4. Now I can successfully ping between H2 and my actual host. However, if I try to run my p4runtime python code, the connection between H2 and the actual host seems broken.
I don’t know what the cause may be, this problem seems wierd to me. Is it because the controller cannot work with the root namespace scenario?
