[Idr] Fwd: I-D Action: draft-chen-idr-asloop-aggr-00.txt

Hi Enke & Stefan,

I have few observations on this draft:

You say:

   Although BCP 172 [RFC6472] makes a recommendation for not using the
   AS_SET path segment in BGP, the AS_SET path segment may remain in use
   for a long time.

Actually RFC6472 goes much further - it discourages use of aggregation from
atomic routes.

Furthermore, isn't the problem you are actually facing very easy to
mitigate by use of different (even private) ASNs in customer's sites ?

The draft is silent on the use case for such essentially significant
and unconditional protocol change.

I hope we are talking about multiple sites - not a single site trying to
learn the aggregate containing its own range.

To me in the light of RFC6472 and all SIDR discussions around it this draft
is trying to move in quite the opposite direction.

Cheers,
Robert

        Title           : Relax the AS Loop Detection for Aggregates in BGP

Abstract:
   Currently an BGP aggregate may be denied or excluded by the AS loop
   detection mechanism when a more specific, contributing route contains
   the local AS number.  To help enhance network robustness and simplify
   network operations, in this document we propose that the AS loop
   detection be relaxed for aggregates with an AS_SET path segment.
