Re: [Idr] new ID on expansion of private use ASN range

Jon,

	Seems reasonable.. I do not fully get the context.. You describe the fact that the increase in the number of AS across both l3VPN and Internet use cases are expanding rapidly.. No Doubt... So I see the creation of the new spaces and ranges.. My concerns are in re the Operations Considerations Section

a) You are creating a set of rules for the internet routing context.

"  If private use ASNs are used and prefixes are originated from these
   private use ASNs which are destined to the Internet, private use ASNs
   must be removed from the AS_PATH before being advertised to the
   global Internet.
"
How does this effect folks who use AS_PATH and/or AS_CONTENT in routing policy decisions? Better question is there an issue if all of the Private ASNs are stripped?

b) You specify no rules in re the L3VPN routing context(s). 

c) Not sure how this would work? If someone screws up what is the collateral damage?

"  Prior to making use of the second, numerically
   higher, range of these ASNs network operators should be confident any
   implementation specific features or filters that recognize private
   use ASNs have been updated to recognize both ranges correctly so that
   no unintended announcement of private use ASNs to the Internet
"

Thanks,

Subject: [Idr] new ID on expansion of private use ASN range

IDR WG folks -

I hope you can take some time from the normal debate(s) to consider and
review a fresh draft on expanding the ASN space reserved for Private
Use.  All comments regarding content, clarity or structure welcome.

Cheers,

Jon

Title:           Autonomous System (AS) Reservation for Private Use
Creation date:   2012-06-20
WG ID:           Individual Submission
Number of pages: 4

Abstract:
   This document describes the reservation of Autonomous System numbers
   (ASNs) that may be used within networks but should not be advertised
   to the Internet, known as private use ASNs.  This document enlarges
   the total space available for private use ASNs by documenting the
   reservation of a second larger range and updates RFC 1930.
