You can set the metric, I think it is done with the ifconfig paramter. I
do not have control over these implicit routes; they are added in by the
kernel.

TerryD says around 2.0.30 they came in before it was the old
ifconfig eth0
route add -net network-address eth0

Again quoting from TerryD they are in /proc/net/rt_local, looking at that
file on my system it appears they have fragmented up the route tables :/
So now rspfd has two tables to look, any other suprises out there?
