Symptoms

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:
https://docs.servicenow.com/csh?topicname=r_DataCollDiscoNWRouteAndSwitch.html&version=latest 

However, this has been seen a few times.

Resolution

Option 1:

01) Disable the following probe:

02) Delete test CI with its associated data. 
03) Run test discoveries to confirm no more duplicates are created. 

Option 2:

01) Disable the SNMP Fields on the SNMP - Routing Probe:

02) Delete test CI with its associated data. 
03) Run test discoveries to confirm no more duplicates are created.
