Authors,

I think I have one question or suggestion.

As you all know some implementations allow you to explicitly force BGP
speaker to keep (pre-policy) all routes/paths received.

Example:

neighbor 192.168.1.1 soft-reconfiguration inbound

The draft does not seem to comment on this case yet if implementation
maintains the above behaviour
at least some of the justifications for the document is gone.

I think that draft should at least mention such behaviour, not force to
change it however put some light that if
configured by the operator some of the benefits of inbound prefix limit
will not be fully effective.

Many thx,
Robert.
