Hi Greg,
I am observing we are partially on the same page.
But if we compare full mesh PE-PE multihop BFD sessions vs PE-ABR then
flooding or DROID to remote PEs don't you think that the latter model is
far more scalable and operationally friendly ?
To make it clear - I am not against PE-PE

Hi Aijun,
I cannot figure out how you draw such a conclusion from my comments to
Robert. You may recall that from very early in the discussion, I was not
enthusiastic, to put it lightly, about either of the solutions. Instead, I
believe that multi-hop BFD should be used to monitor the continuity
Then considering both the scalability and possible false negative of BFD based
solution, can we say that the PUA/UPA solution is more preferable?
