Default route not used when its out and in a a subnet scope

[Dan Shechter]

 Hi All.

I have noticed something regarding routing, and I want to make sure its the
expected behavior.

Lets say I have interface em0 with IP 10.1.1.10/24 and a default route of
10.1.1.1,  then I change em0 IP to 10.1.1.10/31 then change it back to
10.1.1.10/24.

I have noticed that my OBSD 5.0 does not use the default route. I see the
default route in "netstat -nr" and in "route show", but my machine is not
using it.

Then when I do : "route del default" "route add default 1.1.1.1", my
machine starts using the default route again.

Is that normal and to be expected?

Best regards,
Dan
