How to flush route cache in fortigate

Question

Is there something like route cache on fortigate like in linux? How can i clear this cache?

I have some problems with OSPF, after adding or changing redistributed network. Foritgate show routes correctly but traffic from some hosts is going to wrong patch.

Answer 1

From the CLI you can issue the following command to restart the routing service.

exec router restart

To restart OSPF, you can use.

exec router clear ospf process

Answer 2

This might be a little late, but since the question still pops up on the Google search, I thought I answer it.

The following command works in 6.2.7* and above, but does not show up as an argument when trying to auto complete:

diagnose ip rtcache flush

*I don't have a system with a lower FortiOS to test.
