600Mb is going to be really pushing it. I doubt it will be able to handle that kind of throughput.

Even with G2 I would think you would be pushing it.

We're still on the 12.4 train. I do use an ACL with less than 100 
entries which handle BCP38 and block a few bad actors and private IPs 
on the Internet. I will be moving the BCP38 ACL closer to the hosts before the upgrade so the ACL will be a bit 
shorter in the future. We won't be doing any QOS or IPv6 on it but it does take a full BGP table. I just need it to 
last another year or two out of it if possible. I believe this platform goes End of Support in  Spring 2016.

We are looking to double the bandwidth on one of our circuits from 
300Mbps to 600Mbps. We currently use a Cisco 7206VXR with an NPE-G1 card. These seem like very popular routers so 
I'm hoping a few people on this list have them deployed. If you or a customer have these deployed, how much 
bandwidth have you seen them handle? This will be handling dorm traffic at a college so it's mostly download.
The 7206 handles our 300 Mbps circuit just fine, but we are moving it to our 600Mbps circuit. At peak we've seen 
the following numbers for that circuit:


   30 second input rate 559982000 bits/sec, 55809 packets/sec
   30 second output rate 55429000 bits/sec, 32598 packets/sec
      267756984712 packets input, 333325152556755 bytes, 0 no buffer

This is the interface that connects to our provider. As you can see its almost all download traffic. Our ASR1002 
handles it without a sweat but I'm a little skeptical of whether the 7206 will hold up.
This depends on multiple variables. The 7200 is a single-CPU platform 
where CPU can go sky-high when using features like ACL's, QoS, IPv6 and you name it.. Also, changing from IOS 12.4 
to 15 increased our CPU usage with another 10%+. Stick to the bare minimum of features you really need and you will 
be fine.


Full routing and ACL 100+ entries? I would ditch the 7200+NPE-G1 or upgrade to an NPE-G2..
