If none of my switching nodes speak any kind of legacy control plane protocol, yet IRS remains stuffing 500,000 static routes into each (thus programming the network), NPP only makes sense to me if it subsumes the legacy control plane, not co-exists with it as I understand your taxonomy. -Scott > > > Gert > > > > > ----- Original Message ----- > From: irs-discuss-bounces@ietf.org <irs-discuss-bounces@ietf.org> > To: Lenny Giuliano; Alia Atlas > Cc: irs-discuss@ietf.org <irs-discuss@ietf.org> > Sent: Tue Jul 31 01:50:40 2012 > Subject: Re: [irs-discuss] IRS comments > > > [Re-adding IRS] > > Thank you for reviewing and the comments.
