Can you post a brief network diagram indicating the connectivity between the routers and the links?

HI Akber, [Pls Rate if HELPS]

The minimal Fluctuation on Pri in the values of Seconds will not go for the Secondary Fall-back on a General Scenario.

Because for EIGRP, the hold-down Timer has to expire which is 180 in Normal. Reducing the Timers to the minimum is not recommended in design.

Hope I am Informative.

Pls Rate if HELPS

Best Regards,
