Hello,
I'm trying to configure a machine with multiple interface on the same network
(one standard interface and one carp interface).
My problem is that if I set the default routing table to the second interface,
the system can't find it and return "no route" for any distant address
resolution.
The problem occurs even when using to standard iface (so carp is not
involved).
Note that my configuration works perfectly well on OpenBSD 5.7. I did test the
problem with 5.9 and current, and both fail.
Here is my configuration:
--------------- ifconfig

priority: 0

If I change the default route to vio1, it works. The problem occurs only when
the default route is on the second interface (vio2, or carp0 in my cases).
Can someone confirm this is a bug in the routing system ?
