You're welcome to stick around, this is a very nice and unformal community that has always helped me when needed. I try to help too, when I feel I can. Welcome to the gang... Ziv

It's the first time I've used this mailing list and I wasn't sure of what kind of response to expect (I've had mixed experiences of using the official Cisco Support forums) but the volume of detailed replies, advice and personal experiences has been incredibly helpful and much appreciated :o) From: Gert Doering <[email protected]> To: [email protected] Cc: [email protected] Date: 29/06/2011 18:21 Subject: Re: [c-nsp] Replacing a 7206VXR w/ NPE-G1 with Sup720-3BXL w/ WS-X6408A-GBIC Hi, On Wed, Jun 29, 2011 at 04:49:12PM +0100, [email protected] wrote: > Thanks.

The CPU on the Sup720 is slower, so "load a full BGP table from 5 peers" will take longer. OTOH, "100% CPU due to BGP" on the Sup720 doesn't impact packet forwarding capacity, as that's done by other bits of the hardware - so depending on traffic mix and BGP churn (and number of peers) the Sup720 will vastly outperform the NPE-G1 :-) As a reference: we're currently using Sup720s as peering and upstream routers, and we've been quite happy most of the time. Major causes for unhappiness: software bugs (can happen on all platforms), hardware limitations (some things the hardware just cannot do), political issues inside Cisco (6500/7600 in-fighting). gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany [email protected] fax: +49-89-35655025 [email protected] [attachment "att0lq8q.dat" deleted by Matthew Coleman-Hamilton/SBHAM] _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************ The information contained in this e-mail message and its attachments is confidential information intended only for the use of the individual or entity named above.
