Hi Sam,
if path between two VTEPs of the same VXLAN has entropy that BFD MAY exercise,
then there MAY be multiple BFD sessions. I see this as closer to
5884clarification then to 5881.
Regards,
Greg

Does that apply to BFD for VXLAN as well?

Dear All,
I think that this paragraph from Section 2 of RFC 5881 prohibits multiple
single-hop BFD sessions between the same pair of end points:
Each BFD session between a pair of systems MUST traverse a separate
network-layer path in both directions. This is necessary for
demultiplexing to work properly, and also because (by definition)
multiple sessions would otherwise be protecting the same path.
