I was wondering, when it is recommended to use BFD echo.

For example, does it make sense to apply it on underlay and/or overlay BGP.

And Arista CLI offers another bfd feature known as ‘ bfd per-link rfc-7130’, which seems to be applied between two MLAG peers on its port channel.

Arista deployment does also mention Link Fault Signalling and I was wondering to what extend this can be seen as alternative.

I would appreciate any guidance/advice on this matter.

Thanks, Martin
