I am not sure I understand. 

For Echo mode, there is a separate grouping called echo-cfg-parms that allows clients to specify the desired-min-echo-tx-interval and required-min-echo-rx-interval. 

That is somehow different from desired-min-tx-interval and required-min-rx-interval that one can specify for a normal BFD session. For the life of me, I do not understand why the two need to be different :-(. I must be getting amnesia. Maybe one of the co-authors will jog my memory.

Cheers.
