Yes it occurs as standard.

IPFire does not use the FIB table so it is not present but the iproute2 software checks for it by default and the kernel then flags this absence as an error.  
So no actual issue for IPFire but not nice having an error message.

It was raised as an IPFire bug  
[https://bugzilla.ipfire.org/show\_bug.cgi?id=12763](https://bugzilla.ipfire.org/show_bug.cgi?id=12763)

Unfortunately, so far all attempts I have made to the iproute2 software to make it throw away that error message instead of printing it have been unsuccessful.

If anyone else wants to have a go at looking at the iproute2 code to see how to make it do that and submit a patch, they will be very welcome.
