bfd implementation in OVS
i would like some clarification on the BFD implementation in OVS.
http://openvswitch.org/pipermail/discuss/2015-February/016515.html indicates the BFD is not multi-hop but sent through the tunnel.
can someone please clarify, if i create a VXLAN tunnel between 2 OVS switches over a WAN,
1. will the BFD work, i.e will BFD packets be VXLAN encapsulated, and delivered as if it were a single hop?
2. if yes, how does the OVS detect BFD payload after stripping off the VXLAN header on an incoming packet?
3. what does the VTEP put in the inner source and dest IP fields for BFD pkts? does it put the same values as the outer header?
