Keep the default route for 10.10.10.12.

Remove the default route for 10.10.10.11 and replace it with a route 
specific for the 172.x.x.x subnet.  If the first x is always the same 
number, you can use a subnet mask of 255.255.0.0.  You can cover the entire 
private address range with 172.16.0.0 / 255.240.0.0.
