3. This setup uses tinc's "switch" mode: subnets are not assigned in the host files; only Address (for ConnectTo targets only) and the key are required in host files.
-4. It is assumed that the config files go into something like `/etc/tinc/link` and `/etc/tinc/nets.boot` has an entry for "link". The following table can be used to guide configuration of routers. The "routera" configuration for tinc (the master router):
