            Bug ID: 294817
           Summary: sys/netinet/carp:unicast_v4 fails intermittently
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: tests
          Assignee: testing@FreeBSD.org
          Reporter: markj@FreeBSD.org

This test sets up a jail connected to two hosts configured with carp to provide
the virtual address 192.0.2.1.  At one point the jail tries to ping 192.0.2.1,
and it sometimes fails for me.

What seems to happen is that carp_uni_v4_two becomes the carp master, but
routed configures the jail's default route such that the ping goes to the
backup host rather than to the master host.  The backup host doesn't reply, so
the test fails.

I'm not sure how routed decides which host to prefer, but for the test to work
it presumably needs to prefer the carp master host?
