When setting a blackholed static route, the distance is not set correctly. Metric 20 seems to be an FRR default?
Sample config
protocols { static { route 0.0.0.0/8 { blackhole { distance 80 } } } }
'ip ro' command then displays
blackhole 0.0.0.0/8 proto static metric 20
'route -n' also dislayed incorrect metric
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 255.0.0.0 U 20 0 0 *
DHCP distance also does not seem to be applying and defaults to 20
