[c-nsp] Cisco 7304-NSE-100 used as a border BGP router
I have a customer who wishes to be multi-homed with us and another Service Provider and wishes to have 2 full views. We proposed a Cisco 7206VXR-NPE-G1 with 1Gb/256 and the other vendor (a small ISP) provided him with a 7304-NSE-100 and a SPA2-1Gb card as a solution. He has 1Gb with 100Mb commit Metro-E from both providers. Surprisingly, I had never seen a 7304 before used for anything but MPLS tunnel termination. When I looked it up on the Cisco router performance chart is shows the NSE-100 about 3 times the performance of the NPE-G1 but uses PXF instead of just plain old CEF. Questions: 1. What is PXF in comparison to normal CEF? 2. Will this router be able to route 500Mb/sec while processing BGP tables? 3. Is there something special about this 7304 that I am missing? 4. Is the 7304 ok with IPv6 and IPv6 BGP? 5. Is this a good choice for a customer router? Thoughts and comments are appreciated.

Questions: 3. Is there something special about this 7304 that I am missing? It's an old deprecated product which went End of Sale in July 4, 2010. 5. Is this a good choice for a customer router? I would rather choose an ASR1001. It's a modern platform and do out-perform a 7304 in every aspect. As the 7304 is EoS, I can't compare cost, but the ASR1001 is quite reasonably priced. -- Pelle RFC1925, truth 11: Every old idea will be proposed again with a different name and a different presentation, regardless of whether it works. ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

When I looked it up on the Cisco router performance chart is shows the NSE-100 about 3 times the performance of the NPE-G1 but uses PXF instead of just plain old CEF. 3.5Mpps is for single pass, quite many things force two pass and halve performance. The platform is at its best at relatively basic IP termination with QoS, there when compared to VXR it offers superior and predictable performance when VXR and QoS typically at any non-trivial scale spell problems. 1. What is PXF in comparison to normal CEF? PXF is NPU, i.e. application specific hardware, so it has better performance of CPU. CEF means just FIB in cisco speak, but in this context you intend it to mean any software processing. 2.Will this router be able to route 500Mb/sec while processing BGP tables? Yes. But it won't eat full BGP table. 3.Is there something special about this 7304 that I am missing? It's dead platform, as is VXR soon. I wouldn't deploy them, having said that, if someone wants to buy them, I'm happy to sell :. 4.Is the 7304 ok with IPv6 and IPv6 BGP? Yeah it does IPv6 in hardware. 5.Is this a good choice for a customer router? No, it's not particularly good choice anywhere anymore. -- ++ytti ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

We've been fairly happy with some decent QoS deployments on an NPE-G1 and NPE-G2, handling 100's of Mbps. Of course, the software nature of the forwarding paradigm has its limits, but we've surely got lots of bang for our buck :-).
