Agreed. Further, I don’t see the problem with having keepalives at all levels of the stack - at lower levels, they can be suppressed as long as higher levels are performing that function, but it’s still always useful to have them on at lower levels as a “backup”. So I would hesitate to say “do this at the highest level”. My advice would be “do this at ALL levels that benefit, and be sure to suppress independent keepalives at a given level if there is activity at higher levels that suffices”. Joe
