One question I have.
Considering current PolKA Implementation on freeRtr, it can only be run over
a L2 circuit (i.e. a VLAN or direct connection). Or can we run a PolKA tunnel
over a L3 network, similar to VXLAN?
I'm asking this, because there are some sites that are able to reach only 10G
over a L2 circuit but have 100G on a shared internet Link. So if freeRtr is
more flexible we can consume more bandwidth for the experiments.

Regards,

Marcos Schwarz

wcmp was added to the todo.txt and after the the test runs, it's in the todo
too:
https://github.com/rare-freertr/freeRtr/commit/dfcaeb0e5cb085434fa35fc84aa2540b2197f397
until that, you can use multiple tunnels and ecmp... so if you want 1/3-2/3
over 2 paths, then you'll set up 3 tunnels, 1 over 1/3 path, and 2 over 2/3
path...
