An example vRouter using cnet-graph

[maryamtahhan]

Hi Folks

I used FRR and combined it with CNDP to create an example/very simple vRouter which can be found here.

The high level overview of the example is shown below:

NOTE: I was limited to using all virtual interface in my dev env so I had to create a custom BPF program to filter traffic and modify CNDP to load this custom program... It would be great to have the bpfload utility that CNDP used to have back to avoid having to do these things inline in CNDP...

Next steps is to repeat the experiment with physical interfaces between the cndp-frr and frr containers, I have some helper scripts I can share to expose the container namespace then move the physical interface from the host namespace to the container ns...
