Danny's slides were not posted is there an internet draft documenting those
BGP "local" optimizations leading to system wide systemic issues ?

I provided them to the chairs, they are available now.

What is the point of this discussion ?

There are many points.  Mainly that there is room for
improvements in three places: operations and network
architecture, implementations, and BGP itself.

*A* To change reflector spec back to prohibit reflection of paths previously received from the originating client ? Could such recommendation also take
into the account the impact for the reflector itself ?

Sure.

*B* To kill some other work (ADVERTISE_OWN) which while building on
reflecting back to the originating client due it's design not having
anything to do with plain IPv4/IPv6 routes - hence have no local PE box nor
system wide impact ?

See email I sent a moment ago.  Like I said, I have
zero issue with a solution such as that, so long as
implementers aren't planning to change general BGP
behavior to make it easier.

I'll work with a few folks to document several of these
issues in a draft or two, apologies for not having them
available sooner.
