Identification Rule Help for Class: Next Hop Routing Rule

[Wendy Peterson]

Could someone tell me what they have for the Identification Rule for this Class. We have like 2 million of these so I am assuming it needs something else. They are creating duplicates so i'm going thru de-duplication but i'd like to stop them from creating dups.

Thanks

Duplicate Next Hop Routing Rule entries

Cause

The "SNMP - Routing" Probe is being triggered together with the pattern Network Router pattern. The pattern also collects this data, and when this happens, both of them keep creating the duplicates. 

Our documentation says it is ok:

However, this has been seen a few times.
