If you have an Ethernet that is not carrying IP, and want to use BFD you could still wrap the BFD in IP, and pull those packets off by recognising the IP Ethertype. No other protocol on the wire can be using that Ethertype, so there is no ambiguity. You no need to send the payload to an IP handl

It seems there are “20% non-Ethernet at link layer” in the network in question. Therefore I think that IP-based BFD is the only way to address end-to-end connectivity. As Stewart has said, you only need some lightweight IP in your devices to do that. Regards, Sasha Office: +972-39266302 Cell:
