Monitoring a BGP route and AS-PATH.

Hello.

I need to receive a SNMP trap when a BGP route, received with a specific AS-PATH, disappears from routing table.

Any ideas?

Thanks.

You can use EEM for this. Check out the cisco beyond web site for sample scripts that may help you do this.

A company that I used to work for, www.magnus.net had a mature EEM solution for doing this for large network environments. They took a standalone router and using EEM turned it into a route monitor. It would send out notifications when BGP routes of defined attributes like AS-Path diasappeared from routing tables. It was driven by an excel spreadsheet as inputs. It was written by a super CCIE engineer.
