it is important to understand that tinc only takes care for exchanging metadata
(e.g. "subnet" definitions of available hosts).
Thus it is up to you (and probably your "subnet-up" script) to turn these
information into a routing setup.
Probably the following subnet-up script is suitable for many use-cases:

  #!/bin/sh
  ip route add "$SUBNET" dev "$INTERFACE" metric "$WEIGHT" 2>/dev/null || true

Please note the "$WEIGHT" variable (see "man tinc.conf") - it will take care for
the "priority" of the default gateways.

Cheers,
Lars
