[FROG] Filtering kernel routes import

[Tim Weippert]

Hi donald, 

thanks for the answer. 

I had lab systems which get a default route via vagrant but frr 
shouldn't use them as the systems had some bgp peerings where i
simulate an BGP Internet Peering environment.

I solved my issue with the use of an vrf, but badly i can't use bgp
flowspec within the vrf so this test cases aren't usable now (it is not really an
issue ...).

So expecially i would like to remove the kernel default route as within
my simulation is a bgp generated default.

hope this sounds reasonable.

regards, 
tim
