How would you define that EIGRP does not work? Is there a specific route you need to check?
The following link details the EIGRP Mib and what can be checked:
Once we know what to poll, we can easily setup a Trap Rule/Alert and/or a Universal Device Poller + an Advanced Alert to notify you.
So far so good.
But one question remains, can I get a map-object to go red with an advanced rule?
If so I think I (or to be more correct my college) are happy.
What happend once befoure was that the link was up but no EIGRP "notifications" (don't know the term) reached the router so it had no routes to use. You all know what happens then, no traffic.
I have the same issue on my primary network on Qwest MOE.
Our edge routers are connected to Qwest's 3750 Metro switches. The problem arises when the 3750 Metro loses layer 1 connection to the CO. The edge router is still reachable thru the backup network but it will not show any discrepancy since the physical interface between the edge rtr and the metro is still active (albeit no traffic).
Not the cleanest way of doing it but i've setup interface traffic alert that get triggered when traffic on the interface is below certain figure. Also I setup up a Kiwi syslog to report EIGRP neighbor changes thru e-mail. Yes I get tons of email but i'd rather not have the Help Desk tell me that my network is down.
Would also like to see some visual alerting thru the map as well. Can a 0 traffic on an interface trigger a node to go to "unknown" status?
