Correct. Eigrp neighbor connectivity has a short-cut when L2 connectivity goes down, otherwise it will use the eigrp neighbor hold-down timer. You can decrease that timer:

interface fa0/0
  ip hello-interval eigrp p x
  ip hold-time eigrp p y

where p is your eigrp as-number, and x is how often you want the hello (in seconds) and y is the max hold-down timer. Generally y is = x * 3

For some reason when I lose layer 3 connectivity between two managed Ethernet sites EIGRP does not bounce.Is this because the physical interface does not bounce?
