Description gh 2001-03-28 09:50:01 UTC

There is a problem to insert a route to a specific interface
on the local network if the route to the net have dissapeard.

There should be a switch to "route" to insert the hardware to
send to

route add 192.168.36.52 -hw 00:80:c8:d3:3c:f4

Fix: 

ifconfig vr0 inet 192.158.36.51
route delete 192.168.3
ping -c 1 192.168.36.526.0 (don't work)

And there is no way to insert the route to the interface in
the routing table

route add 192.168.36.52 -interface vr0

gives the local ether address in the routing table
(This should be resolved by arp?)

The  net.link.ether.inet.useloopback=0 don't seems to be honored.

GH
How-To-Repeat: ifconfig vr0 inet 192.158.36.51
ping -c 1 192.168.36.52
route delete 192.168.36.0
ping -c 1 192.168.36.52       (Still works since a entry in route table is there)
