Your description looks very similar to the scenario where our networks
have been deployed. Even the landscape in the pictures is similar :)

The main difference is we're using bmx6 for routing among the multiple
mesh clouds.

Thanks for your detailed answer to the survey!

We can talk in more detail in the specific list which I saw you've
already subscribed to.

Un abrazo,
