"BGP Routing Neighbors Defined But Not Peering" ... is an out of the box alert that comes with NPM. I need to do the same thing but with EIGRP neighbors, not with BGP.
There are several historical threads in the forums here that seem to match discussions on EIGRP but are locked and archived and I cannot see them.
If I have Tunnel X, and the eigrp neighbor on that tunnel goes down / unreachable, I need to generate an alert. (These are Cisco 4221 routers)
Thanks in advance for your help!
