Hi,

I was going to stay out of this, but then you went and picked on me.

If you look back a few years, you will find the discussion of IS-IS purge 
origination TLV.  Part of that was a band-aid to counter the fact that the 
original protocol allowed any system to purge anything at any time for any 
reason.  This was basically an undebuggable problem as any system in the area 
could have triggered it.

Just because both use the word ‘proxy’ doesn’t mean that they have anything to 
do with one another.  In Area Proxy, it is VERY clear who the actor is: the 
area leader. All systems have elected this.

Because you create a race condition and you create a traceability problem.  And 
there are already simpler ways of solving this without protocol additions.
