Correct. Eigrp neighbor connectivity has a short-cut when L2 connectivity g=
oes 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 =3D x * 3

For some reason when I lose layer 3 connectivity between two managed Ethern=

not bounce?
