Main connection (CDN or similar) and BackUp (Dialer over ISDN).
In case of DOWN of the main line, EIGRP with static-floating-route is fast enough to quickly switch to the Back-Up line. And also to switch back, when the main line return UP.
BUT in case of continuous UP/DOWN of the main line, I have a lot of trouble caused by the switching to the back-up line and back again.
I am searching a parameter to configure in the EIGRP or in OSPF (a "wait-time") to waiting a while, to become the main line stable for a defined time (some minuts) before switching back.

Hi,
If you are using Dialer-Watch you can use the command below.
"dialer watch-disable seconds" - Apply a disable delay time to the interface. After the primary interface recovers, this delay prevents disconnecting the backup interface for the specified time period. This delay timer is started when the idle timer expires, and the status of the primary route is checked and found to be up. This delay can ensure stability, especially for flapping interfaces or interfaces experiencing frequent route changes.
HTH,

Try the following:
interface BRI0/0
ip address yy.yy.yy.yy 255.255.255.0
encapsulation ppp
dialer idle-timeout 180
dialer fast-idle 180
dialer map ip xx.xx.xx.xx name ABC 1234567
dialer-group 1
isdn switch-type basic-net3
ppp authentication chap
