I think this is impossible. As the name suggests. The defaultroute is
the route taken, when no other route applies. If you have two of them
your webservers would have two alternatives with no default. Further, on
what should they decide which one of both roots to use?
There is no feature known to me, which allow the router to tell other
machines how much load it has or that it should choose another one. You
woud have to reconfigure your routing tables on your webservers at any
time the load-balancer decides he has enough to do.
The load-balancer has to decide. When you have two of them distribute
your webserver over both in a static manner.
