What you're looking for are the route metrics, stored in the routing
table.  Use "netstat -nar" to see which routes have been cached.  You
should be able to delete the metrics associated with a cloned route by
doing "route delete ipaddress".

These would have nothing to do with what you're seeing.  Keepalive only
applies to established connections which are sitting idle.  As you are
disconnecting and reconnecting, only the route metrics are relevant.
