Thanks for replies on the default-address-selection. Now that that
is working, I'm having further issues in attempts to get
sampling and flow export working.

The flow collector, on a directly connected VLAN, does not
receive any flow packets. I see the following things:

wbenb@bba> show route 195.121.224.125

inet.0: 111157 destinations, 111157 routes (111148 active, 8 holddown, 3
hidden)
+ = Active Route, - = Last Active, * = Both

    }
}

Trying 195.121.224.125...

mysterious...any ideas?

Thanks,
BB
