Have you seen this?
R5 should advertise default network to CAT1 only when it looses it connection to interface ser0/0.
The first part works. R5 advertises the default route on the right condition. (when s0/0 goes down)
But when s0/0 goes up, CAT1 does not cease to receive default route from R5. It seems IOS gets lost on the way back to remove the advertisement of default route, although the static default route disappears
from R5 RIB.
R5 s0/0 is configured with backup interface dialer 200 and has a default network pointing to dialer200.
When R5 looses s0/0, dialer 200 goes up, static default route is installed on R5 RIB and default route is advertised to CAT1.

CAT1 receives the default when serial 0/0 goes down but when s0/0 goes up CAT1 does not cease to receive the default:
