For some reason, the BFD did not receive the health check packet on time (that could be due to many reasons.). When that happened the BFD state went down and then the OSPF has converged.

Based on the outputs provided the BFD is configured to 300ms and applied to both OSPF vlans "IP_41" and "IP_InterEx".

Are those vlans/ports direct connected to the OSPF neighbor switch/router?

[Sergey_Vekli]

Maybe it caused by enabling bgp for multicast. No other global changes in config.

enable bfd vlan "IP_InterEx"
configure bfd vlan "IP_InterEx" receive-interval 100 transmit-interval 100
enable bfd vlan "IP_41"
configure bfd vlan "IP_41" receive-interval 100 transmit-interval 100
configure ospf vlan IP_41 bfd on
configure ospf vlan IP_InterEx bfd on

[Henrique]

Did you start to see this issue after any change like configuration, firmware upgrade or that has started without any change?

Could you please share the outputs below:

show configuration | include bfd
show bfd
show bfd counters
show bfd session detail

Now we again have error in log. Why BFD path down at same time for all 2 neighbors?

Hi. No. We don't use RSVP.
