In this article we'll using freeRouter setup deployed in #002 and replace the pcapInt providing freeRouter native software dataplane with P4Lang's dataplane. Actually the effective dataplane is ensured P4lang virtual simple_switch_grpc running RARE P4 program called: router.p4.

In our example we will use the same debian stable image (buster) installed as a VirtualBox VM as in #002.

- had a demonstration of how to integrate freeRouter into a local area network (Similar to article #002)
- However instead of using pcapInt you are now using a software P4 dataplane from P4lang project: bmv2
- BMv2 simple_switch_grpc target is used an run RARE router.p4
- communication between freeRouter control plane and bmv2 is ensured by pcapInt via veth pair [ veth250 - veth251 ]
- This communication is possible via RARE forwarder.py based on GRPC P4Lang P4Runtime python binding
- In this example the BMv2 P4 switch has only 1 dataplane interface that is bound to enp0s9 VM interface exposed to the local network as a bridged interface
