Hi Acee, When we met we agreed to have a new model for clients. Afterwards I decided to create a new types module, and still went ahead with the clients module. I am fine with having everything in the types module (no client module).
I am not sure I fully understand your comment/question on bfd-client-ext-cfg-parms/bfd-grouping-common-cfg-parms. The reason we have 2 groupings is that some protocols may decide to have just the enable leaf and others may also want the multiplier/timer. Regards, Reshad.
