Como o FortiOS seleciona uma rota
- A policy route is consulted BEFORE the routing table and overrides it. If the table says one thing and traffic does another, look for a policy route first — this tool models the table, not policy routes.
- DISTANCE decides which route is INSTALLED. Routes to the same destination compete, the lowest distance wins, and the loser is absent from the table rather than merely deprioritised.
- PRIORITY decides which of several ALREADY-INSTALLED routes is preferred. It never resurrects a route that lost on distance.
- Same prefix and same distance means both install and priority chooses. Different distances means one installs and the other is a floating backup.
- Forwarding takes the LONGEST matching prefix among installed routes. True ties on prefix, distance and priority are load shared by ECMP.
- destination: 10.2.5.10
- route: prefix=0.0.0.0/0, gw=192.0.2.1, dev=wan1, distance=10, priority=0
- route: prefix=10.2.0.0/16, gw=10.1.1.1, dev=port3, distance=10, priority=0
