Hi,
I'm still having this problem with many different OPNSense instances.
I connect OPNSense to remote devices via VTI IPSEC tunnels, then run OSPF over them and all works fine. But sometimes, most of time when IPSECs go down and then are restored, the routes received by OSPF are reported under routing->diagnostics->OSPF (so FRR is loading them), but are missing under system->routes->status, so they are not (re)loaded and networking is broken.
This is really strange for me, but I cannot find a solution nor any idea. Help will be really appreciate.
Do you find anything in the frr debug logs when it happens?
