Title: FRR monitoring
Post by: pcaetano on January 13, 2026, 11:41:18 AM
Hi all,

I'm testing opnsense to set up a ipsec vti tunnel + bgp peering to a cloud provider and the solution works cleanly, but I'd like to set up route monitoring to verify tunnel status and what prefixes are being announced vs prefixes being filtered.
How are you monitoring FRR advertised/received prefixes on your OPNsense firewalls?

It looks like net-snmp plugin does not populate the relevant OIDs to export the prefixes.
I'm currently fetching that information via API calls, but it seems a bit cumbersome.

Thanks in advance,
Pedro

Eventually I've found a OID that allows me to monitor this via snmp and avoid exposing the API.
From what I understand, it is not possible to expose it read-only or restrict it to diagnostics page.
snmpwalk -v2c -c public 127.0.0.1 1.3.6.1.2.1.15.3.1
