It is a best practice to create black hole routes with destinations set to each branch network. If the FortiGate temporarily loses connectivity with a branch network, traffic destined to that network is sent to the black hole until connectivity has been restored.

Each Black hole route includes:
  • Setting dst to the branch network IP address
  • Setting the distance to 254

config router static

edit 1

set dst 10.0.0.0/14

set distance 254

set blackhole enable

next

end
