RE: eigrp and managed ethernet
The issue may be that only one direction of traffic is being impacted. So maybe your A end is receiving all the hellos, while the Z end is not. Therefore A still has Z as a neighbor, but Z doesn't have A as a neighbor.

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 <[EMAIL PROTECTED]> To: Philip Lavine <[EMAIL PROTECTED]>; nanog <[EMAIL PROTECTED]> 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:[EMAIL PROTECTED] 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?

Is there an engineer at Hurrican Electric that could contact me off list? It looks like you may have a static route to my network that you are advertising out via AS 6939. It's preventing several customers from connecting to us.

Re: [NANOG] Hurrican Electric
Mike, I was able to get someone else from Hurricane on and they resolved the issue quickly. Thanks for the response.

Independent Testing for Network Hardware
Can anyone recommend a reliable independent testing company that tests network hardware performance? We are considering buying testing hardware (right now we are looking at Spirent TestCenter) and I wanted to see if there were other options... Brian Knoll
