Be sure to differentiate between unicast and multicast reachability. Try 'ping 224.0.0.10'. Stephen Kratzer On Tuesday 23 September 2008 12:25:34 Philip Lavine wrote:
What is really bizarre is that I am down for minutes not seconds and the timers never fire. If I don't manually passive the connection eigrp will for some reason think there is a neighbor even though I am unable to source ping across the WAN.

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?
