Hi Dale,

At an IXP, it's fine for a client network operator to voluntarily shut
down their bgp sessions, as noted in section 3.1, and let traffic drain
off an interface.  This is the standard operational practice.

Graceful shutdown and Shutdown Communication could be used, but they're
new and are arguably overkill in many situations because for the most
part, network flaps are a part of life and people aren't interested in
what's going on in other peoples' networks unless it affects their own.

The point of the ID is that it's about session culling / involuntary
session drops initiated by the IXP Caretaker, and I think we need to
stay on topic in the draft, rather than get bogged down in tangential stuff.
