Are you 100% positive that the link is really not passing any traffic? Have you looked at interface stats to verify that there are no incoming packets? I'd suggest running some EIGRP debug commands during the outage to verify if you are really not getting any packets..

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. ----- Original Message ---- From: Matthew Huff <mhuff@ox.com> To: Philip Lavine <source_route@yahoo.com>; nanog <nanog@merit.edu> Sent: Tuesday, September 23, 2008 8:59:14 AM Subject: RE: eigrp and managed ethernet 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 http://www.cisco.com/en/US/docs/ios/12_2/iproute/command/reference/1rfeigrp.... ---- Matthew Huff | One Manhattanville Rd OTA Management LLC | Purchase, NY 10577 www.ox.com | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-460-4139 -----Original Message----- From: Philip Lavine [mailto:source_route@yahoo.com] Sent: Tuesday, September 23, 2008 11:43 AM To: nanog Subject: eigrp and managed ethernet 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?
