Our engineering team has settled on three $20k/node options: - Sup720-3BXLs with PS and fan upgrades
Still quite slow CPU wise. RSP's are supposed to be a lot faster and actually usable.
- Sup2s as switches + ISIS + statics and no BGP, push BGP edge routing off to NPE-G2s across a 2-3Gbps port-channel
The NPE-G2 - even an NPE-G1 - will do all that BGP stuff easily; the CPU is fast enough. But...you might be in for a bad surprise concerning the Portchannel. Remember - it's done in software. So, depending on your packet sizes, you might experience a throughput _drop_ once you bundle. My experiments were done with very small packets though (DNS queries and responses, avg. packet size around 140 Byte). The devices I tested were the 1RU models (7301 for NPE-G1 and 7201 for NPE-G2). In "unbundled mode" they pushed around 940 kpps (G1) and 1320 kpps (G2) with CPU loads between 85% and 100%. Channel bundling took a lot out of the boxes. 7301 keeled over at 470, 7201 at 660 kpps. If you're only pushing big packets, though... Yours, Elmar.
