Hi Harald, I think you need to take a step back from looking at kit and consider your network design more carefully. For this, you need to start out not with a list of features that you want, but with a network design which will deliver the services that your customers need. So rather than talking about whether to upgrade from a vxr+npe-g2 to a c7600, you probably want to think about what's the best way to handle your broadband termination service, how many customer edge ports do you need and how many peering / transit sessions you need and of what speed. Once you do this, you can then create a network with separate devices for each service. So your broadband aggregation should probably be moved from c2800 to npe-g1, or if that's too small then you might want to consider an asr1000; if you want a small number of 10G transit / peering sessions to your network, then ASR9001 might be good. If you need lots of GE edge ports, then depending on profile maybe you could do this on a shared 10G router port on say an ASR9k downlinking into an me3600, or if they are all very high bandwidth, you might want to look at a 20x1G card for the asr9k. It really depends on your need. I'd steer clear of spending money on c7600/c6500. From what I can tell, they are not cisco's primary development platforms at this stage, and it's likely that the asr9k will provide a much longer service lifetime. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
