That would be where the NPE-G1 would be better than an RSP8; however what I don't like is when you rely on the internal switching of the NPE-G1 you end up creating a 1-slot router with the PAs then becoming substandard additions. I understand that money is an issue, but the original question was about backbone use and I would rather go with a 7603 or a 7606 instead of a 7206VXR. Michel.

Isn't it somewhat wrong to compare the NPE-G1 to any RSP since most of the packets, most of the time, are handled by the processors on the VIPs and never bother the RSP other than flowing through its SRAM? Or at least a comparison should be NPE-G1 vs some combination of RSP and VIPs. If you take a 7500 as far as you can (RSP16, VIP6-80s), then how does it compare to a 7206VXR/NPE-G1? Cisco plainly admits that the GEIP tops out at around 400mbit/s, but it's based on the rather old VIP2-50. Anyone know if they plan to put out a more capable GEIP, perhaps based on the VIP6-80, which theoretically would double the GEIP's throughput? ---------------------------------------------------------------------- Jon Lewis *jlewis@lewis.org*| I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

I don't know how much more capable it is, but the GEIP+ is based on the VIP4. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
