Thank you for your reply
At present, bmv2 and p4c have been deployed on an industrial PC, but there are some problems when using it as a p4 switch.I refer to the information you provide, as well as a link (Getting Started with P4 - Open Networking Foundation).
I run the following command line:
sudo simple_switch --interface 0@enp2s0 --interface 1@enp4s0 test.bmv2/test.json &
table_add ipv4_match to_port_action 10.10.0.0/16 => 0
table_add ipv4_match to_port_action 11.11.0.0/16 => 1
I plan to link two windows hosts through P4siwtch, with the following topology:
windows PC<----wired link----> industrial PC<----wired link---->windows PC
10.10.1.2___________ enp2s0(P4 Switch)enp4s0___________11.11.1.2
windows PC can’t ping each other successfully,But I capture packet information on industrial PC by wireshark（It shows correct source address）.And I followed the links above to complete the whole experiment, which passed correctly…
But two physical hosts cannot communicate. Why is this?
Shouldn’t I bind the physical port directly to the virtual switch side?
The experiment on a physical machine is closer to the real world ,as we intend to simulate the effect of a p4 switch in a data center to assist computing services.but faces some difficulties.
