You may want to check out BFD for EIGRP, http://www.cisco.com/en/US/technologies/tk648/tk365/tk207/technologies_white_paper0900aecd80243fe7_ps6599_Products_White_Paper.html Regards, Kevin On Tue, Sep 23, 2008 at 11:25 AM, Philip Lavine <source_route () yahoo com> 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. ----- 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.html ---- 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?
