Static routes have the lowest administrative distances by default, other than locally connected routes. This default administrative distance value is 10, which can be changed.
Static routes have a default metric value of 10, which also can be changed. If you have multiple static routes to the same destination, you can make one preferable over the other by changing the metric.
Path monitoring monitors upstream interfaces on remote, reliable devices using ICMP pings. If the path monitoring fails, an associated static route is removed from the routing table. An alternative route then can be used to route traffic.
NOTE: default administrative distance is 10 and default metric is 10, the static route with the lowest metric is added to FIB.
The firewall initially populates its learned routes into the firewall’s IP routing information base (RIB). The virtual router obtains the best route from the RIB, and then places it in the forwarding information base (FIB). Packets then are forwarded to the next hop router defined in the FIB.
Static routes are not learned routes, they are added directly to the FIB.
