    Switch X670. BDF flapping on all peers. We enable log debug-mode for bfd. (In this log problem start at 1:50). And we can't find trigger for this behaviour.

    Hi,

    did you check the GTAC Kownledge article BFD session DOWN messages seen when the “Rx” & “Tx” intervals are configured within 200ms?

    I don't think it caused by link detection. All peers is down in same time and no LACP in our case, we use single links.
