If a carrier circuit goes down, and hands off on an NTU, no interface goes down if the carrier circuit drops.

You need to monitor physical interface, on the switch.

For any Metro/carrier circuit, you will not lose link if the circuit goes down.
I can't think of anything else to monitor, other than bps across the link to catch this.

OSPF/ISIS are link-state.
Why don't you monitor only the interface that is running it?

I've had a think about this..
As it's not BGP, you can't alert on peer state, but if you define a neighbour's via entity match, such as "router-id match 10.10.*", you could do a "exists eq true" for the test, or "status eq full"

ISIS would be pretty much the same as OSPF


Thoughts?

How would one go about alerting for these?

The problem we have with most of the things we don't currently alert on is simply that it's not obvious *how* we should alert on them.

Are there any plans to add an alert checker for OSPF/IGP Neighbor state changes? The BGP alerts checkers are great, however I'm looking for a similar thing for IGP.

Alternatively,
Does anyone know of a solution for alerting IGP neighbour state changes? I have 100-200 routers I would need to monitor.

Thanks in advance,

Ben
