Collecting information on irb's with the API

Help
1

I wish to collect information on irb’s in Splunk using the API, so that I can relate vrfs to vlans in my cmdb in Splunk. But I can’t find what endpoint I need to use to get the irb information.
How can I do this?

Is the information available in LibreNMS currently? Where?
If not, is the information available via SNMP? What MIB and OID(s)?

Thank you for your reply. In the meantime we managed to find a way of mapping vrf to vlan.
