The entry with flags "UC" is a "cloning route" which instructs the
kernel to perform ARP/ND and insert llinfo routes. Typically these are
Without the C route for the subnet, a packet will still match the
default route, but then there is no route for the IP addess of the
gateway. Without a C route and without a UHLc route, there is no way to
arp. It's the C route that directs that the prefix should be handled
by arping (and on which interface).
So when you are flushing routes, don't delete that one.
