The BFD implementation in OVS is mainly used for tunnel link failure
detection. You need to have a tunnel port first and then can you enable
bfd on the tunnel port. The BFD state machine in OVS will compose/send
control packets through the tunnel... No OpenFlow rules are involved...
We currently do not support multi-hop bfd.
However, at this time, it is still unclear what kind of link
(tunnel/point-to-point physical link) you want you monitor... maybe you
should clarify first,
