I'm not familiar with this tap0 type of interface, but if you have any
default routes in place when bringing up your ppp interface, the ppp
default route will not override the existing default route. You'll
need to make sure there are no default routes in place before bringing
up the ppp interface. You don't have to take eth0 down, just remove
the existing default route prior to pon. This will allow ppp to set
the default route to the ppp0 interface.
Will having a default route to ppp0 solve your routing problem. Or,
do you need to add specific static routes to take advantage of having
multiple interfaces?
